From 8616e0fc1e27295316f9821a883f0e9fa6f8200f Mon Sep 17 00:00:00 2001

Subject: [PATCH 0001/1002] cifs: remove unneeded NULL checks from
cifs_show_options
show_options is always called with the namespace_sem held. Therefore we
don't need to worry about the vfsmount being NULL, or it vanishing while
the function is running. By the same token, there's no need to worry
about the superblock, tcon, smb or tcp sessions being NULL on entry.

one region ends exactly before the second region begins. This is no
overlap but the function returned true in that case.

Subject: [PATCH 0009/1002] dma-debug: Put all hash-chain locks into the same
lock class
Alan Cox reported that lockdep runs out of its stack-trace entries
with certain configs:
BUG: MAX_STACK_TRACE_ENTRIES too low
This happens because there are 1024 hash buckets, each with a
separate lock. Lockdep puts each lock into a separate lock class and
tracks them independently.
But in reality we never take more than one of the buckets, so they
really belong into a single lock-class. Annotate the has bucket lock
init accordingly.
[ Impact: reduce the lockdep footprint of dma-debug ]

Subject: [PATCH 0013/1002] drm/i915: Change I2C api to pass around
i2c_adapters
The existing API passed around intel_i2c_chan pointers, which are dependent
on the i2c bit-banging algo. This precluded the driver from using outputs
which use a different algo. Switching to the more general i2c_adpater allows
the driver to support non bit-banging DDC.
This also required moving the slave address into the output private
structures.

Subject: [PATCH 0018/1002] drm/i915: Split array of DAC limits into separate
structures.
The array of DAC limits was only ever referenced with #defined constant
offsets, and keeping those #define values in sync with the array itself was a
nuisance. This will make future changes to the set of DAC limits less
error-prone.

Subject: [PATCH 0021/1002] drm/i915: Generate 2MHz clock for display port aux
channel I/O. Retry I/O.
The display port aux channel clock is taken from the hrawclk value, which is
provided to the chip as the FSB frequency (as far as I can determine). The
strapping values for that are available in the CLKCFG register, now used to
select an appropriate divider to generate a 2MHz clock.
In addition, the DisplayPort spec requires that each aux channel I/O be
retried 'at least 3 times' in case the sink is idle when the first request
comes in.

Subject: [PATCH 0022/1002] x86: Set cpu_llc_id on AMD CPUs
This counts when building sched domains in case NUMA information
is not available.
( See cpu_coregroup_mask() which uses llc_shared_map which in turn is
created based on cpu_llc_id. )
Currently Linux builds domains as follows:
(example from a dual socket quad-core system)
CPU0 attaching sched-domain:
domain 0: span 0-7 level CPU
groups: 0 1 2 3 4 5 6 7
...
CPU7 attaching sched-domain:
domain 0: span 0-7 level CPU
groups: 7 0 1 2 3 4 5 6
Ever since that is borked for multi-core AMD CPU systems.
This patch fixes that and now we get a proper:
CPU0 attaching sched-domain:
domain 0: span 0-3 level MC
groups: 0 1 2 3
domain 1: span 0-7 level CPU
groups: 0-3 4-7
...
CPU7 attaching sched-domain:
domain 0: span 4-7 level MC
groups: 7 4 5 6
domain 1: span 0-7 level CPU
groups: 4-7 0-3
This allows scheduler to assign tasks to cores on different sockets
(i.e. that don't share last level cache) for performance reasons.

Subject: [PATCH 0024/1002] perf_counter tools: Fix vmlinux fallback when
running on a different kernel
Lucas De Marchi reported that perf report and perf annotate
displays mismatching profile if a perf.data is analyzed on
an older kernel - even if the correct vmlinux is specified
via the -k option.
The reason is the fallback path in util/symbol.c:dso__load_kernel():
int dso__load_kernel(struct dso *self, const char *vmlinux,
symbol_filter_t filter, int verbose)
{
int err = -1;
if (vmlinux)
err = dso__load_vmlinux(self, vmlinux, filter, verbose);
if (err)
err = dso__load_kallsyms(self, filter, verbose);
return err;
}
dso__load_vmlinux() returns negative on error, but on success it
returns the number of symbols loaded - which confuses the function
to load the kallsyms.
This is normally harmless, as reporting is usually performed on the
same kernel that is analyzed - but if there's a mismatch then we
load the wrong kallsyms and create a non-sensical symbol tree.
The fix is to only fall back to kallsyms on errors.

Subject: [PATCH 0026/1002] exofs: Remove IBM copyrights
Boaz,
Congrats on getting all the OSD stuff into 2.6.30!
I just pulled the git, and saw that the IBM copyrights are still there.
Please remove them from all files:
* Copyright (C) 2005, 2006
* International Business Machines
IBM has revoked all rights on the code - they gave it to me.
Thanks!

Subject: [PATCH 0027/1002] exofs: Avoid using file_fsync()
The use of file_fsync() in exofs_file_sync() is not necessary since it
does some extra stuff not used by exofs. Open code just the parts that
are currently needed.
TODO: Farther optimization can be done to sync the sb only on inode
update of new files, Usually the sb update is not needed in exofs.

In pcpu_unmap(), flushing virtual cache on vunmap can't be delayed as
the page is going to be returned to the page allocator. Only TLB
flushing can be put off such that vmalloc code can handle it lazily.
Fix it.

Subject: [PATCH 0031/1002] x86: rename remap percpu first chunk allocator to
lpage
The "remap" allocator remaps large pages to build the first chunk;
however, the name isn't very good because 4k allocator remaps too and
the whole point of the remap allocator is using large page mapping.
The allocator will be generalized and exported outside of x86, rename
it to lpage before that happens.
percpu_alloc kernel parameter is updated to accept both "remap" and
"lpage" for lpage allocator.

Subject: [PATCH 0032/1002] x86: prepare setup_pcpu_lpage() for pageattr fix
Make the following changes in preparation of coming pageattr updates.
* Define and use array of struct pcpul_ent instead of array of
pointers. The only difference is ->cpu field which is set but
unused yet.
* Rename variables according to the above change.
* Rename local variable vm to pcpul_vm and move it out of the
function.

Subject: [PATCH 0034/1002] x86: fix pageattr handling for lpage percpu
allocator and re-enable it
lpage allocator aliases a PMD page for each cpu and returns whatever
is unused to the page allocator. When the pageattr of the recycled
pages are changed, this makes the two aliases point to the overlapping
regions with different attributes which isn't allowed and known to
cause subtle data corruption in certain cases.
This can be handled in simliar manner to the x86_64 highmap alias.
pageattr code should detect if the target pages have PMD alias and
split the PMD alias and synchronize the attributes.
pcpur allocator is updated to keep the allocated PMD pages map sorted
in ascending address order and provide pcpu_lpage_remapped() function
which binary searches the array to determine whether the given address
is aliased and if so to which address. pageattr is updated to use
pcpu_lpage_remapped() to detect the PMD alias and split it up as
necessary from cpa_process_alias().
Jan Beulich spotted the original problem and incorrect usage of vaddr
instead of laddr for lookup.
With this, lpage percpu allocator should work correctly. Re-enable
it.

Subject: [PATCH 0035/1002] x86: implement percpu_alloc kernel parameter
According to Andi, it isn't clear whether lpage allocator is worth the
trouble as there are many processors where PMD TLB is far scarcer than
PTE TLB. The advantage or disadvantage probably depends on the actual
size of percpu area and specific processor. As performance
degradation due to TLB pressure tends to be highly workload specific
and subtle, it is difficult to decide which way to go without more
data.
This patch implements percpu_alloc kernel parameter to allow selecting
which first chunk allocator to use to ease debugging and testing.
While at it, make sure all the failure paths report why something
failed to help determining why certain allocator isn't working. Also,
kill the "Great future plan" comment which had already been realized
quite some time ago.

Subject: [PATCH 0036/1002] x86: ensure percpu lpage doesn't consume too much
vmalloc space
On extreme configuration (e.g. 32bit 32-way NUMA machine), lpage
percpu first chunk allocator can consume too much of vmalloc space.
Make it fall back to 4k allocator if the consumption goes over 20%.
[ Impact: add sanity check for lpage percpu first chunk allocator ]

Subject: [PATCH 0039/1002] perf_counter tools: Introduce alias member in
event_symbol
By introducing alias member in event_symbol :
1. duplicate lines are removed, like:
cpu-cycles and cycles
branch-instructions and branches
context-switches and cs
cpu-migrations and migrations
2. We can also add alias for another events.
Now ./perf list looks like :
List of pre-defined events (to be used in -e):
cpu-cycles OR cycles [Hardware event]
instructions [Hardware event]
cache-references [Hardware event]
cache-misses [Hardware event]
branch-instructions OR branches [Hardware event]
branch-misses [Hardware event]
bus-cycles [Hardware event]
cpu-clock [Software event]
task-clock [Software event]
page-faults [Software event]
faults [Software event]
minor-faults [Software event]
major-faults [Software event]
context-switches OR cs [Software event]
cpu-migrations OR migrations [Software event]

Subject: [PATCH 0043/1002] drm/i915: correct suspend/resume ordering
We need to save register state *after* idling GEM, clearing the ring,
and uninstalling the IRQ handler, or we might end up saving bogus
fence regs, for one. Our restore ordering should already be correct,
since we do GEM, ring and IRQ init after restoring the last register
state, which prevents us from clobbering things.
I put this together to potentially address a bug, but I haven't heard
back if it fixes it yet. However I think it stands on its own, so I'm
sending it in.

Subject: [PATCH 0044/1002] drm/i915: Add support for changing LVDS panel
fitting using an output property.
Previously the driver would always scale the chosen video mode to fill the
panel. This adds 1:1 and maintain-aspect-ratio scaling modes.
v2: the drm_calloc/drm_free is replaced by kzalloc/kfree based
on Eric's suggestion.

Subject: [PATCH 0045/1002] drm/i915: Don't change the blank/sync width when
calculating scaled modes
Also, use the border instead of border minus one.
At the same time, make sure the horizontal border and hsync are even for
the LVDS that works in dual-channel mode. So both horizontal border and hsync
start are also changed to be even, even for the LVDS in single-channel mode.

Subject: [PATCH 0048/1002] drm/i915: set TV detection mode when tv is already
connected
We used load_detect_temp flag to determine whether to set tv to the test
mode. However if the TV already has a mode set, we still need to set the
test mode to determine connection. This results in blinking, but there is
no other reliable way to determine TV connection.

Subject: [PATCH 0049/1002] drm/i915: fix LFP data fetch
Apparently the proper way to do this is to use the LFP data pointer
block to figure out the LFP data block entry size, then use that plus
the panel index to calculate an offset into the LFP data block array.
Similar fix has already been pushed to the 2D driver to fix fdo bug
applied to the VBIOS reader, and things look sane).

Subject: [PATCH 0052/1002] x86: Move init_gbpages() to setup_arch()
The init_gbpages() function is conditionally called from
init_memory_mapping() function. There are two call-sites where
this 'after_bootmem' condition can be true: setup_arch() and
mem_init() via pci_iommu_alloc().
Therefore, it's safe to move the call to init_gbpages() to
setup_arch() as it's always called before mem_init().
This removes an after_bootmem use - paving the way to remove
all uses of that state variable.

Subject: [PATCH 0054/1002] perf_counter tools: Handle overlapping MMAP events
Martin Schwidefsky reported "perf report" symbol resolution
problems on S390.
Since we only report MMAP, not MUNMAP, we have to deal with
overlapping maps.
We used to simply throw out the old map on the assumption whole
maps got unmapped. This obviously doesn't deal with partial
unmaps. However it appears some dynamic linkers do fancy
partial unmaps (s390), so do something more elaborate and
truncate the old maps, only removing them when they've been
fully covered.
This resolves (part of) the S390 symbol resolution problems.

Subject: [PATCH 0055/1002] perf_counter: Optimize perf_swcounter_event()
Similar to tracepoints, use an enable variable to reduce
overhead when unused.
Only look for a counter of a particular event type when we know
there is at least one in the system.

Remove the child_counter->atrr.inherit = 1 line because the

Subject: [PATCH 0057/1002] perf_counter: Optimize perf_counter_alloc()'s
inherit case
We don't need to add usage counts for swcounter and attr usage
models for inherited counters since the parent counter will
always have one, which suffices to generate the needed output.
This avoids up to 3 global atomic increments per inherited
counter.

Some of the N770's MMC configuration options seem to have been
dropped. This patch adds them back in again.
Note that only the .ocr_mask change was /critical/, but I've added the
.max_freq setting back as well, as the original sources had it. Can
anyone confirm if this is unnecessary?
Secondly, there is support in the original code for a 4wire/higher
speed mode. As I don't have the requisite N770 hardware (I think it
was a rev2 N770?) to test this, I can't really add it back.

The omap_type() function is added and returns the DEVICETYPE field of
the CONTROL_STATUS register. The result can be used for conditional
code based on whether device is GP (general purpose), EMU or
HS (high security). Also move the type defines so omap1 code
compile does not require ifdefs for sections using these defines.
This code is needed for the following fix to set the SRAM
size correctly for HS omaps. Also at least PM and watchdog
code will need this function.

Subject: [PATCH 0072/1002] powerpc/qe: add polling timeout to qe_issue_cmd()
The qe_issue_cmd() function (Freescale PowerPC QUICC Engine library) polls
on a register until a status bit changes, but does not include a timeout
to handle the situation if the bit never changes. Change the code to use
the new spin_event_timeout() macro, which simplifies polling on a register
without a timeout.

@@ -1238,1122 +1238,7 @@ descriptions for the SOC devices for which new nodes have been
defined; this list will expand as more and more SOC-containing
platforms are moved over to use the flattened-device-tree model.
- a) PHY nodes
-
- Required properties:
-
- - device_type : Should be "ethernet-phy"
- - interrupts : <a b> where a is the interrupt number and b is a
- field that represents an encoding of the sense and level
- information for the interrupt. This should be encoded based on
- the information in section 2) depending on the type of interrupt
- controller you have.
- - interrupt-parent : the phandle for the interrupt controller that
- services interrupts for this device.
- - reg : The ID number for the phy, usually a small integer
- - linux,phandle : phandle for this node; likely referenced by an
- ethernet controller node.
-
-
- Example:
-
- ethernet-phy@0 {
- linux,phandle = <2452000>
- interrupt-parent = <40000>;
- interrupts = <35 1>;
- reg = <0>;
- device_type = "ethernet-phy";
- };
-
-
- b) Interrupt controllers
-
- Some SOC devices contain interrupt controllers that are different
- from the standard Open PIC specification. The SOC device nodes for
- these types of controllers should be specified just like a standard
- OpenPIC controller. Sense and level information should be encoded
- as specified in section 2) of this chapter for each device that
- specifies an interrupt.
-
- Example :
-
- pic@40000 {
- linux,phandle = <40000>;
- interrupt-controller;
- #address-cells = <0>;
- reg = <40000 40000>;
- compatible = "chrp,open-pic";
- device_type = "open-pic";
- };
-
- c) 4xx/Axon EMAC ethernet nodes
-
- The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
- the Axon bridge. To operate this needs to interact with a ths
- special McMAL DMA controller, and sometimes an RGMII or ZMII
- interface. In addition to the nodes and properties described
- below, the node for the OPB bus on which the EMAC sits must have a
- correct clock-frequency property.
-
- i) The EMAC node itself
-
- Required properties:
- - device_type : "network"
-
- - compatible : compatible list, contains 2 entries, first is
- "ibm,emac-CHIP" where CHIP is the host ASIC (440gx,
- 405gp, Axon) and second is either "ibm,emac" or
- "ibm,emac4". For Axon, thus, we have: "ibm,emac-axon",
- "ibm,emac4"
- - interrupts : <interrupt mapping for EMAC IRQ and WOL IRQ>
- - interrupt-parent : optional, if needed for interrupt mapping
- - reg : <registers mapping>
- - local-mac-address : 6 bytes, MAC address
- - mal-device : phandle of the associated McMAL node
- - mal-tx-channel : 1 cell, index of the tx channel on McMAL associated
- with this EMAC
- - mal-rx-channel : 1 cell, index of the rx channel on McMAL associated
- with this EMAC
- - cell-index : 1 cell, hardware index of the EMAC cell on a given
- ASIC (typically 0x0 and 0x1 for EMAC0 and EMAC1 on
- each Axon chip)
- - max-frame-size : 1 cell, maximum frame size supported in bytes
- - rx-fifo-size : 1 cell, Rx fifo size in bytes for 10 and 100 Mb/sec
- operations.
- For Axon, 2048
- - tx-fifo-size : 1 cell, Tx fifo size in bytes for 10 and 100 Mb/sec
- operations.
- For Axon, 2048.
- - fifo-entry-size : 1 cell, size of a fifo entry (used to calculate
- thresholds).
- For Axon, 0x00000010
- - mal-burst-size : 1 cell, MAL burst size (used to calculate thresholds)
- in bytes.
- For Axon, 0x00000100 (I think ...)
- - phy-mode : string, mode of operations of the PHY interface.
- Supported values are: "mii", "rmii", "smii", "rgmii",
- "tbi", "gmii", rtbi", "sgmii".
- For Axon on CAB, it is "rgmii"
- - mdio-device : 1 cell, required iff using shared MDIO registers
- (440EP). phandle of the EMAC to use to drive the
- MDIO lines for the PHY used by this EMAC.
- - zmii-device : 1 cell, required iff connected to a ZMII. phandle of
- the ZMII device node
- - zmii-channel : 1 cell, required iff connected to a ZMII. Which ZMII
- channel or 0xffffffff if ZMII is only used for MDIO.
- - rgmii-device : 1 cell, required iff connected to an RGMII. phandle
- of the RGMII device node.
- For Axon: phandle of plb5/plb4/opb/rgmii
- - rgmii-channel : 1 cell, required iff connected to an RGMII. Which
- RGMII channel is used by this EMAC.
- Fox Axon: present, whatever value is appropriate for each
- EMAC, that is the content of the current (bogus) "phy-port"
- property.
-
- Optional properties:
- - phy-address : 1 cell, optional, MDIO address of the PHY. If absent,
- a search is performed.
- - phy-map : 1 cell, optional, bitmap of addresses to probe the PHY
- for, used if phy-address is absent. bit 0x00000001 is
- MDIO address 0.
- For Axon it can be absent, though my current driver
- doesn't handle phy-address yet so for now, keep
- 0x00ffffff in it.
- - rx-fifo-size-gige : 1 cell, Rx fifo size in bytes for 1000 Mb/sec
- operations (if absent the value is the same as
- rx-fifo-size). For Axon, either absent or 2048.
- - tx-fifo-size-gige : 1 cell, Tx fifo size in bytes for 1000 Mb/sec
- operations (if absent the value is the same as
- tx-fifo-size). For Axon, either absent or 2048.
- - tah-device : 1 cell, optional. If connected to a TAH engine for
- offload, phandle of the TAH device node.
- - tah-channel : 1 cell, optional. If appropriate, channel used on the
- TAH engine.
-
- Example:

- cell-index = <0>;
- max-frame-size = <5dc>;
- rx-fifo-size = <1000>;
- tx-fifo-size = <800>;
- phy-mode = "rmii";
- phy-map = <00000001>;
- zmii-device = <&ZMII0>;
- zmii-channel = <0>;
- };
-
- ii) McMAL node
-
- Required properties:
- - device_type : "dma-controller"
- - compatible : compatible list, containing 2 entries, first is
- "ibm,mcmal-CHIP" where CHIP is the host ASIC (like
- emac) and the second is either "ibm,mcmal" or
- "ibm,mcmal2".
- For Axon, "ibm,mcmal-axon","ibm,mcmal2"
- - interrupts : <interrupt mapping for the MAL interrupts sources:
- 5 sources: tx_eob, rx_eob, serr, txde, rxde>.
- For Axon: This is _different_ from the current
- firmware. We use the "delayed" interrupts for txeob
- and rxeob. Thus we end up with mapping those 5 MPIC
- interrupts, all level positive sensitive: 10, 11, 32,
- 33, 34 (in decimal)
- - dcr-reg : < DCR registers range >
- - dcr-parent : if needed for dcr-reg
- - num-tx-chans : 1 cell, number of Tx channels
- - num-rx-chans : 1 cell, number of Rx channels
-
- iii) ZMII node
-
- Required properties:
- - compatible : compatible list, containing 2 entries, first is
- "ibm,zmii-CHIP" where CHIP is the host ASIC (like
- EMAC) and the second is "ibm,zmii".
- For Axon, there is no ZMII node.
- - reg : <registers mapping>
-
- iv) RGMII node
-
- Required properties:
- - compatible : compatible list, containing 2 entries, first is
- "ibm,rgmii-CHIP" where CHIP is the host ASIC (like
- EMAC) and the second is "ibm,rgmii".
- For Axon, "ibm,rgmii-axon","ibm,rgmii"
- - reg : <registers mapping>
- - revision : as provided by the RGMII new version register if
- available.
- For Axon: 0x0000012a
-
- d) Xilinx IP cores
-
- The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
- in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
- of standard device types (network, serial, etc.) and miscellaneous
- devices (gpio, LCD, spi, etc). Also, since these devices are
- implemented within the fpga fabric every instance of the device can be
- synthesised with different options that change the behaviour.
-
- Each IP-core has a set of parameters which the FPGA designer can use to
- control how the core is synthesized. Historically, the EDK tool would
- extract the device parameters relevant to device drivers and copy them
- into an 'xparameters.h' in the form of #define symbols. This tells the
- device drivers how the IP cores are configured, but it requres the kernel
- to be recompiled every time the FPGA bitstream is resynthesized.
-
- The new approach is to export the parameters into the device tree and
- generate a new device tree each time the FPGA bitstream changes. The
- parameters which used to be exported as #defines will now become
- properties of the device node. In general, device nodes for IP-cores
- will take the following form:
-
- (name): (generic-name)@(base-address) {
- compatible = "xlnx,(ip-core-name)-(HW_VER)"
- [, (list of compatible devices), ...];
- reg = <(baseaddr) (size)>;
- interrupt-parent = <&interrupt-controller-phandle>;
- interrupts = < ... >;
- xlnx,(parameter1) = "(string-value)";
- xlnx,(parameter2) = <(int-value)>;
- };
-
- (generic-name): an open firmware-style name that describes the
- generic class of device. Preferably, this is one word, such
- as 'serial' or 'ethernet'.
- (ip-core-name): the name of the ip block (given after the BEGIN
- directive in system.mhs). Should be in lowercase
- and all underscores '_' converted to dashes '-'.
- (name): is derived from the "PARAMETER INSTANCE" value.
- (parameter#): C_* parameters from system.mhs. The C_ prefix is
- dropped from the parameter name, the name is converted
- to lowercase and all underscore '_' characters are
- converted to dashes '-'.
- (baseaddr): the baseaddr parameter value (often named C_BASEADDR).
- (HW_VER): from the HW_VER parameter.
- (size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
-
- Typically, the compatible list will include the exact IP core version
- followed by an older IP core version which implements the same
- interface or any other device with the same interface.
-
- 'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
-
- For example, the following block from system.mhs:
-
- BEGIN opb_uartlite
- PARAMETER INSTANCE = opb_uartlite_0
- PARAMETER HW_VER = 1.00.b
- PARAMETER C_BAUDRATE = 115200
- PARAMETER C_DATA_BITS = 8
- PARAMETER C_ODD_PARITY = 0
- PARAMETER C_USE_PARITY = 0
- PARAMETER C_CLK_FREQ = 50000000
- PARAMETER C_BASEADDR = 0xEC100000
- PARAMETER C_HIGHADDR = 0xEC10FFFF
- BUS_INTERFACE SOPB = opb_7
- PORT OPB_Clk = CLK_50MHz
- PORT Interrupt = opb_uartlite_0_Interrupt
- PORT RX = opb_uartlite_0_RX
- PORT TX = opb_uartlite_0_TX
- PORT OPB_Rst = sys_bus_reset_0
- END
-
- becomes the following device tree node:
-
- opb_uartlite_0: serial@ec100000 {
- device_type = "serial";
- compatible = "xlnx,opb-uartlite-1.00.b";
- reg = <ec100000 10000>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <1 0>; // got this from the opb_intc parameters
- current-speed = <d#115200>; // standard serial device prop
- clock-frequency = <d#50000000>; // standard serial device prop
- xlnx,data-bits = <8>;
- xlnx,odd-parity = <0>;
- xlnx,use-parity = <0>;
- };
-
- Some IP cores actually implement 2 or more logical devices. In
- this case, the device should still describe the whole IP core with
- a single node and add a child node for each logical device. The
- ranges property can be used to translate from parent IP-core to the
- registers of each device. In addition, the parent node should be
- compatible with the bus type 'xlnx,compound', and should contain
- #address-cells and #size-cells, as with any other bus. (Note: this
- makes the assumption that both logical devices have the same bus
- binding. If this is not true, then separate nodes should be used
- for each logical device). The 'cell-index' property can be used to
- enumerate logical devices within an IP core. For example, the
- following is the system.mhs entry for the dual ps2 controller found
- on the ml403 reference design.
-
- BEGIN opb_ps2_dual_ref
- PARAMETER INSTANCE = opb_ps2_dual_ref_0
- PARAMETER HW_VER = 1.00.a
- PARAMETER C_BASEADDR = 0xA9000000
- PARAMETER C_HIGHADDR = 0xA9001FFF
- BUS_INTERFACE SOPB = opb_v20_0
- PORT Sys_Intr1 = ps2_1_intr
- PORT Sys_Intr2 = ps2_2_intr
- PORT Clkin1 = ps2_clk_rx_1
- PORT Clkin2 = ps2_clk_rx_2
- PORT Clkpd1 = ps2_clk_tx_1
- PORT Clkpd2 = ps2_clk_tx_2
- PORT Rx1 = ps2_d_rx_1
- PORT Rx2 = ps2_d_rx_2
- PORT Txpd1 = ps2_d_tx_1
- PORT Txpd2 = ps2_d_tx_2
- END
-
- It would result in the following device tree nodes:
-
- opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "xlnx,compound";
- ranges = <0 a9000000 2000>;
- // If this device had extra parameters, then they would
- // go here.
- ps2@0 {
- compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
- reg = <0 40>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <3 0>;
- cell-index = <0>;
- };
- ps2@1000 {
- compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
- reg = <1000 40>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <3 0>;
- cell-index = <0>;
- };
- };
-
- Also, the system.mhs file defines bus attachments from the processor
- to the devices. The device tree structure should reflect the bus
- attachments. Again an example; this system.mhs fragment:
-

- reg = <d1000fc0 20>;
- };
- };
- };
-
- That covers the general approach to binding xilinx IP cores into the
- device tree. The following are bindings for specific devices:
-
- i) Xilinx ML300 Framebuffer
-
- Simple framebuffer device from the ML300 reference design (also on the
- ML403 reference design as well as others).
-
- Optional properties:
- - resolution = <xres yres> : pixel resolution of framebuffer. Some
- implementations use a different resolution.
- Default is <d#640 d#480>
- - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
- Default is <d#1024 d#480>.
- - rotate-display (empty) : rotate display 180 degrees.
-
- ii) Xilinx SystemACE
-
- The Xilinx SystemACE device is used to program FPGAs from an FPGA
- bitstream stored on a CF card. It can also be used as a generic CF
- interface device.
-
- Optional properties:
- - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
-
- iii) Xilinx EMAC and Xilinx TEMAC
-
- Xilinx Ethernet devices. In addition to general xilinx properties
- listed above, nodes for these devices should include a phy-handle
- property, and may include other common network device properties
- like local-mac-address.
-
- iv) Xilinx Uartlite
-
- Xilinx uartlite devices are simple fixed speed serial ports.
-
- Required properties:
- - current-speed : Baud rate of uartlite
-
- v) Xilinx hwicap
-
- Xilinx hwicap devices provide access to the configuration logic
- of the FPGA through the Internal Configuration Access Port
- (ICAP). The ICAP enables partial reconfiguration of the FPGA,
- readback of the configuration information, and some control over
- 'warm boots' of the FPGA fabric.
-
- Required properties:
- - xlnx,family : The family of the FPGA, necessary since the
- capabilities of the underlying ICAP hardware
- differ between different families. May be
- 'virtex2p', 'virtex4', or 'virtex5'.
-
- vi) Xilinx Uart 16550
-
- Xilinx UART 16550 devices are very similar to the NS16550 but with
- different register spacing and an offset from the base address.
-
- Required properties:
- - clock-frequency : Frequency of the clock input
- - reg-offset : A value of 3 is required
- - reg-shift : A value of 2 is required
-
- e) USB EHCI controllers
-
- Required properties:
- - compatible : should be "usb-ehci".
- - reg : should contain at least address and length of the standard EHCI
- register set for the device. Optional platform-dependent registers
- (debug-port or other) can be also specified here, but only after
- definition of standard EHCI registers.
- - interrupts : one EHCI interrupt should be described here.
- If device registers are implemented in big endian mode, the device
- node should have "big-endian-regs" property.
- If controller implementation operates with big endian descriptors,
- "big-endian-desc" property should be specified.
- If both big endian registers and descriptors are used by the controller
- implementation, "big-endian" property can be specified instead of having
- both "big-endian-regs" and "big-endian-desc".
-
- Example (Sequoia 440EPx):
- ehci@e0000300 {
- compatible = "ibm,usb-ehci-440epx", "usb-ehci";
- interrupt-parent = <&UIC0>;
- interrupts = <1a 4>;
- reg = <0 e0000300 90 0 e0000390 70>;
- big-endian;
- };
-
- f) MDIO on GPIOs
-
- Currently defined compatibles:
- - virtual,gpio-mdio
-
- MDC and MDIO lines connected to GPIO controllers are listed in the
- gpios property as described in section VIII.1 in the following order:
-
- MDC, MDIO.
-
- Example:
-
- mdio {
- compatible = "virtual,mdio-gpio";
- #address-cells = <1>;
- #size-cells = <0>;
- gpios = <&qe_pio_a 11
- &qe_pio_c 6>;
- };
-
- g) SPI (Serial Peripheral Interface) busses
-
- SPI busses can be described with a node for the SPI master device
- and a set of child nodes for each SPI slave on the bus. For this
- discussion, it is assumed that the system's SPI controller is in
- SPI master mode. This binding does not describe SPI controllers
- in slave mode.
-
- The SPI master node requires the following properties:
- - #address-cells - number of cells required to define a chip select
- address on the SPI bus.
- - #size-cells - should be zero.
- - compatible - name of SPI bus controller following generic names
- recommended practice.
- No other properties are required in the SPI bus node. It is assumed
- that a driver for an SPI bus device will understand that it is an SPI bus.
- However, the binding does not attempt to define the specific method for
- assigning chip select numbers. Since SPI chip select configuration is
- flexible and non-standardized, it is left out of this binding with the
- assumption that board specific platform code will be used to manage
- chip selects. Individual drivers can define additional properties to
- support describing the chip select layout.
-
- SPI slave nodes must be children of the SPI master node and can
- contain the following properties.
- - reg - (required) chip select address of device.
- - compatible - (required) name of SPI device following generic names
- recommended practice
- - spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
- - spi-cpol - (optional) Empty property indicating device requires
- inverse clock polarity (CPOL) mode
- - spi-cpha - (optional) Empty property indicating device requires
- shifted clock phase (CPHA) mode
- - spi-cs-high - (optional) Empty property indicating device requires
- chip select active high
-
- SPI example for an MPC5200 SPI bus:
- spi@f00 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,mpc5200b-spi","fsl,mpc5200-spi";
- reg = <0xf00 0x20>;
- interrupts = <2 13 0 2 14 0>;
- interrupt-parent = <&mpc5200_pic>;
-
- ethernet-switch@0 {
- compatible = "micrel,ks8995m";
- spi-max-frequency = <1000000>;
- reg = <0>;
- };
-
- codec@1 {
- compatible = "ti,tlv320aic26";
- spi-max-frequency = <100000>;
- reg = <1>;
- };

-VII - Marvell Discovery mv64[345]6x System Controller chips
-===========================================================
-
-The Marvell mv64[345]60 series of system controller chips contain
-many of the peripherals needed to implement a complete computer
-system. In this section, we define device tree nodes to describe
-the system controller chip itself and each of the peripherals
-which it contains. Compatible string values for each node are
-prefixed with the string "marvell,", for Marvell Technology Group Ltd.
-
-1) The /system-controller node
-
- This node is used to represent the system-controller and must be
- present when the system uses a system controller chip. The top-level
- system-controller node contains information that is global to all
- devices within the system controller chip. The node name begins
- with "system-controller" followed by the unit address, which is
- the base address of the memory-mapped register set for the system
- controller chip.
-
- Required properties:
-
- - ranges : Describes the translation of system controller addresses
- for memory mapped registers.
- - clock-frequency: Contains the main clock frequency for the system
- controller chip.
- - reg : This property defines the address and size of the
- memory-mapped registers contained within the system controller
- chip. The address specified in the "reg" property should match
- the unit address of the system-controller node.
- - #address-cells : Address representation for system controller
- devices. This field represents the number of cells needed to
- represent the address of the memory-mapped registers of devices
- within the system controller chip.
- - #size-cells : Size representation for for the memory-mapped
- registers within the system controller chip.
- - #interrupt-cells : Defines the width of cells used to represent
- interrupts.
-
- Optional properties:
-
- - model : The specific model of the system controller chip. Such
- as, "mv64360", "mv64460", or "mv64560".
- - compatible : A string identifying the compatibility identifiers
- of the system controller chip.
-
- The system-controller node contains child nodes for each system
- controller device that the platform uses. Nodes should not be created
- for devices which exist on the system controller chip but are not used
-
- Example Marvell Discovery mv64360 system-controller node:
-
- system-controller@f1000000 { /* Marvell Discovery mv64360 */
- #address-cells = <1>;
- #size-cells = <1>;
- model = "mv64360"; /* Default */
- compatible = "marvell,mv64360";
- clock-frequency = <133333333>;
- reg = <0xf1000000 0x10000>;
- virtual-reg = <0xf1000000>;
- ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
- 0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
- 0xa0000000 0xa0000000 0x4000000 /* User FLASH */

-
-2) Child nodes of /system-controller
-
- a) Marvell Discovery MDIO bus
-
- The MDIO is a bus to which the PHY devices are connected. For each

-
- b) Marvell Discovery ethernet controller
-
- The Discover ethernet controller is described with two levels
- of nodes. The first level describes an ethernet silicon block
- and the second level describes up to 3 ethernet nodes within

- registers for the node are interleaved within a single set
- of registers. The "ethernet-block" level describes the
- shared register set, and the "ethernet" nodes describe ethernet
- port-specific properties.

+ 4xx/Axon EMAC ethernet nodes
+
+ The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
+ the Axon bridge. To operate this needs to interact with a ths
+ special McMAL DMA controller, and sometimes an RGMII or ZMII
+ interface. In addition to the nodes and properties described
+ below, the node for the OPB bus on which the EMAC sits must have a
+ correct clock-frequency property.

+ - mdio-device : 1 cell, required iff using shared MDIO registers
+ (440EP). phandle of the EMAC to use to drive the
+ MDIO lines for the PHY used by this EMAC.

+Marvell Discovery mv64[345]6x System Controller chips
+===========================================================
+
+The Marvell mv64[345]60 series of system controller chips contain
+many of the peripherals needed to implement a complete computer
+system. In this section, we define device tree nodes to describe
+the system controller chip itself and each of the peripherals
+which it contains. Compatible string values for each node are
+prefixed with the string "marvell,", for Marvell Technology Group Ltd.
+
+1) The /system-controller node
+
+ This node is used to represent the system-controller and must be
+ present when the system uses a system controller chip. The top-level
+ system-controller node contains information that is global to all
+ devices within the system controller chip. The node name begins
+ with "system-controller" followed by the unit address, which is
+ the base address of the memory-mapped register set for the system
+ controller chip.
+
+ Required properties:
+
+ - ranges : Describes the translation of system controller addresses
+ for memory mapped registers.
+ - clock-frequency: Contains the main clock frequency for the system
+ controller chip.
+ - reg : This property defines the address and size of the
+ memory-mapped registers contained within the system controller
+ chip. The address specified in the "reg" property should match
+ the unit address of the system-controller node.
+ - #address-cells : Address representation for system controller
+ devices. This field represents the number of cells needed to
+ represent the address of the memory-mapped registers of devices
+ within the system controller chip.
+ - #size-cells : Size representation for for the memory-mapped
+ registers within the system controller chip.
+ - #interrupt-cells : Defines the width of cells used to represent
+ interrupts.
+
+ Optional properties:
+
+ - model : The specific model of the system controller chip. Such
+ as, "mv64360", "mv64460", or "mv64560".
+ - compatible : A string identifying the compatibility identifiers
+ of the system controller chip.
+
+ The system-controller node contains child nodes for each system
+ controller device that the platform uses. Nodes should not be created
+ for devices which exist on the system controller chip but are not used
+
+ Example Marvell Discovery mv64360 system-controller node:
+
+ system-controller@f1000000 { /* Marvell Discovery mv64360 */
+ #address-cells = <1>;
+ #size-cells = <1>;
+ model = "mv64360"; /* Default */
+ compatible = "marvell,mv64360";
+ clock-frequency = <133333333>;
+ reg = <0xf1000000 0x10000>;
+ virtual-reg = <0xf1000000>;
+ ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
+ 0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
+ 0xa0000000 0xa0000000 0x4000000 /* User FLASH */
+ 0x00000000 0xf1000000 0x0010000 /* Bridge's regs */
+ 0xf2000000 0xf2000000 0x0040000>;/* Integrated SRAM */
+
+ [ child node definitions... ]
+ }
+
+2) Child nodes of /system-controller
+
+ a) Marvell Discovery MDIO bus
+
+ The MDIO is a bus to which the PHY devices are connected. For each
+ device that exists on this bus, a child node should be created. See
+ the definition of the PHY node below for an example of how to define
+ a PHY.
+
+ Required properties:
+ - #address-cells : Should be <1>
+ - #size-cells : Should be <0>
+ - device_type : Should be "mdio"
+ - compatible : Should be "marvell,mv64360-mdio"

+
+ mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ device_type = "mdio";
+ compatible = "marvell,mv64360-mdio";
+
+ ethernet-phy@0 {
+ ......
+ };
+ };
+
+
+ b) Marvell Discovery ethernet controller
+
+ The Discover ethernet controller is described with two levels
+ of nodes. The first level describes an ethernet silicon block
+ and the second level describes up to 3 ethernet nodes within
+ that block. The reason for the multiple levels is that the
+ registers for the node are interleaved within a single set
+ of registers. The "ethernet-block" level describes the
+ shared register set, and the "ethernet" nodes describe ethernet
+ port-specific properties.

+SPI (Serial Peripheral Interface) busses
+
+SPI busses can be described with a node for the SPI master device
+and a set of child nodes for each SPI slave on the bus. For this
+discussion, it is assumed that the system's SPI controller is in
+SPI master mode. This binding does not describe SPI controllers
+in slave mode.
+
+The SPI master node requires the following properties:
+- #address-cells - number of cells required to define a chip select
+ address on the SPI bus.
+- #size-cells - should be zero.
+- compatible - name of SPI bus controller following generic names
+ recommended practice.
+No other properties are required in the SPI bus node. It is assumed
+that a driver for an SPI bus device will understand that it is an SPI bus.
+However, the binding does not attempt to define the specific method for
+assigning chip select numbers. Since SPI chip select configuration is
+flexible and non-standardized, it is left out of this binding with the
+assumption that board specific platform code will be used to manage
+chip selects. Individual drivers can define additional properties to
+support describing the chip select layout.
+
+SPI slave nodes must be children of the SPI master node and can
+contain the following properties.
+- reg - (required) chip select address of device.
+- compatible - (required) name of SPI device following generic names
+ recommended practice
+- spi-max-frequency - (required) Maximum SPI clocking speed of device in Hz
+- spi-cpol - (optional) Empty property indicating device requires
+ inverse clock polarity (CPOL) mode
+- spi-cpha - (optional) Empty property indicating device requires
+ shifted clock phase (CPHA) mode
+- spi-cs-high - (optional) Empty property indicating device requires
+ chip select active high

+ d) Xilinx IP cores
+
+ The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
+ in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
+ of standard device types (network, serial, etc.) and miscellaneous
+ devices (gpio, LCD, spi, etc). Also, since these devices are
+ implemented within the fpga fabric every instance of the device can be
+ synthesised with different options that change the behaviour.
+
+ Each IP-core has a set of parameters which the FPGA designer can use to
+ control how the core is synthesized. Historically, the EDK tool would
+ extract the device parameters relevant to device drivers and copy them
+ into an 'xparameters.h' in the form of #define symbols. This tells the
+ device drivers how the IP cores are configured, but it requres the kernel
+ to be recompiled every time the FPGA bitstream is resynthesized.
+
+ The new approach is to export the parameters into the device tree and
+ generate a new device tree each time the FPGA bitstream changes. The
+ parameters which used to be exported as #defines will now become
+ properties of the device node. In general, device nodes for IP-cores
+ will take the following form:
+
+ (name): (generic-name)@(base-address) {
+ compatible = "xlnx,(ip-core-name)-(HW_VER)"
+ [, (list of compatible devices), ...];
+ reg = <(baseaddr) (size)>;
+ interrupt-parent = <&interrupt-controller-phandle>;
+ interrupts = < ... >;
+ xlnx,(parameter1) = "(string-value)";
+ xlnx,(parameter2) = <(int-value)>;
+ };
+
+ (generic-name): an open firmware-style name that describes the
+ generic class of device. Preferably, this is one word, such
+ as 'serial' or 'ethernet'.
+ (ip-core-name): the name of the ip block (given after the BEGIN
+ directive in system.mhs). Should be in lowercase
+ and all underscores '_' converted to dashes '-'.
+ (name): is derived from the "PARAMETER INSTANCE" value.
+ (parameter#): C_* parameters from system.mhs. The C_ prefix is
+ dropped from the parameter name, the name is converted
+ to lowercase and all underscore '_' characters are
+ converted to dashes '-'.
+ (baseaddr): the baseaddr parameter value (often named C_BASEADDR).
+ (HW_VER): from the HW_VER parameter.
+ (size): the address range size (often C_HIGHADDR - C_BASEADDR + 1).
+
+ Typically, the compatible list will include the exact IP core version
+ followed by an older IP core version which implements the same
+ interface or any other device with the same interface.
+
+ 'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
+
+ For example, the following block from system.mhs:
+
+ BEGIN opb_uartlite
+ PARAMETER INSTANCE = opb_uartlite_0
+ PARAMETER HW_VER = 1.00.b
+ PARAMETER C_BAUDRATE = 115200
+ PARAMETER C_DATA_BITS = 8
+ PARAMETER C_ODD_PARITY = 0
+ PARAMETER C_USE_PARITY = 0
+ PARAMETER C_CLK_FREQ = 50000000
+ PARAMETER C_BASEADDR = 0xEC100000
+ PARAMETER C_HIGHADDR = 0xEC10FFFF
+ BUS_INTERFACE SOPB = opb_7
+ PORT OPB_Clk = CLK_50MHz
+ PORT Interrupt = opb_uartlite_0_Interrupt
+ PORT RX = opb_uartlite_0_RX
+ PORT TX = opb_uartlite_0_TX
+ PORT OPB_Rst = sys_bus_reset_0
+ END
+
+ becomes the following device tree node:
+
+ opb_uartlite_0: serial@ec100000 {
+ device_type = "serial";
+ compatible = "xlnx,opb-uartlite-1.00.b";
+ reg = <ec100000 10000>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <1 0>; // got this from the opb_intc parameters
+ current-speed = <d#115200>; // standard serial device prop
+ clock-frequency = <d#50000000>; // standard serial device prop
+ xlnx,data-bits = <8>;
+ xlnx,odd-parity = <0>;
+ xlnx,use-parity = <0>;
+ };
+
+ Some IP cores actually implement 2 or more logical devices. In
+ this case, the device should still describe the whole IP core with
+ a single node and add a child node for each logical device. The
+ ranges property can be used to translate from parent IP-core to the
+ registers of each device. In addition, the parent node should be
+ compatible with the bus type 'xlnx,compound', and should contain
+ #address-cells and #size-cells, as with any other bus. (Note: this
+ makes the assumption that both logical devices have the same bus
+ binding. If this is not true, then separate nodes should be used
+ for each logical device). The 'cell-index' property can be used to
+ enumerate logical devices within an IP core. For example, the
+ following is the system.mhs entry for the dual ps2 controller found
+ on the ml403 reference design.
+
+ BEGIN opb_ps2_dual_ref
+ PARAMETER INSTANCE = opb_ps2_dual_ref_0
+ PARAMETER HW_VER = 1.00.a
+ PARAMETER C_BASEADDR = 0xA9000000
+ PARAMETER C_HIGHADDR = 0xA9001FFF
+ BUS_INTERFACE SOPB = opb_v20_0
+ PORT Sys_Intr1 = ps2_1_intr
+ PORT Sys_Intr2 = ps2_2_intr
+ PORT Clkin1 = ps2_clk_rx_1
+ PORT Clkin2 = ps2_clk_rx_2
+ PORT Clkpd1 = ps2_clk_tx_1
+ PORT Clkpd2 = ps2_clk_tx_2
+ PORT Rx1 = ps2_d_rx_1
+ PORT Rx2 = ps2_d_rx_2
+ PORT Txpd1 = ps2_d_tx_1
+ PORT Txpd2 = ps2_d_tx_2
+ END
+
+ It would result in the following device tree nodes:
+
+ opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "xlnx,compound";
+ ranges = <0 a9000000 2000>;
+ // If this device had extra parameters, then they would
+ // go here.
+ ps2@0 {
+ compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
+ reg = <0 40>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <3 0>;

+ };

+ reg = <1000 40>;
+ interrupt-parent = <&opb_intc_0>;
+ interrupts = <3 0>;
+ cell-index = <0>;
+ };
+ };
+
+ Also, the system.mhs file defines bus attachments from the processor
+ to the devices. The device tree structure should reflect the bus
+ attachments. Again an example; this system.mhs fragment:
+
+ BEGIN ppc405_virtex4
+ PARAMETER INSTANCE = ppc405_0
+ PARAMETER HW_VER = 1.01.a
+ BUS_INTERFACE DPLB = plb_v34_0
+ BUS_INTERFACE IPLB = plb_v34_0
+ END

+ END
+

+ PARAMETER C_RNG3_HIGHADDR = 0xDFFFFFFF
+ BUS_INTERFACE SPLB = plb_v34_0
+ BUS_INTERFACE MOPB = opb_v20_0
+ END
+
+ Gives this device tree (some properties removed for clarity):
+
+ plb@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "xlnx,plb-v34-1.02.a";

+ }
+
+ opb@20000000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <20000000 20000000 20000000

+ };
+
+ opb_intc_0: interrupt-controller@d1000fc0 {
+ reg = <d1000fc0 20>;
+ };
+ };
+ };
+
+ That covers the general approach to binding xilinx IP cores into the
+ device tree. The following are bindings for specific devices:
+
+ i) Xilinx ML300 Framebuffer
+
+ Simple framebuffer device from the ML300 reference design (also on the
+ ML403 reference design as well as others).
+
+ Optional properties:
+ - resolution = <xres yres> : pixel resolution of framebuffer. Some
+ implementations use a different resolution.
+ Default is <d#640 d#480>
+ - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
+ Default is <d#1024 d#480>.
+ - rotate-display (empty) : rotate display 180 degrees.
+
+ ii) Xilinx SystemACE
+
+ The Xilinx SystemACE device is used to program FPGAs from an FPGA
+ bitstream stored on a CF card. It can also be used as a generic CF
+ interface device.
+
+ Optional properties:
+ - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
+
+ iii) Xilinx EMAC and Xilinx TEMAC
+
+ Xilinx Ethernet devices. In addition to general xilinx properties
+ listed above, nodes for these devices should include a phy-handle
+ property, and may include other common network device properties
+ like local-mac-address.
+
+ iv) Xilinx Uartlite
+
+ Xilinx uartlite devices are simple fixed speed serial ports.
+
+ Required properties:
+ - current-speed : Baud rate of uartlite
+
+ v) Xilinx hwicap
+
+ Xilinx hwicap devices provide access to the configuration logic
+ of the FPGA through the Internal Configuration Access Port
+ (ICAP). The ICAP enables partial reconfiguration of the FPGA,
+ readback of the configuration information, and some control over
+ 'warm boots' of the FPGA fabric.
+
+ Required properties:
+ - xlnx,family : The family of the FPGA, necessary since the
+ capabilities of the underlying ICAP hardware
+ differ between different families. May be
+ 'virtex2p', 'virtex4', or 'virtex5'.
+
+ vi) Xilinx Uart 16550
+
+ Xilinx UART 16550 devices are very similar to the NS16550 but with
+ different register spacing and an offset from the base address.
+
+ Required properties:
+ - clock-frequency : Frequency of the clock input
+ - reg-offset : A value of 3 is required
+ - reg-shift : A value of 2 is required

Subject: [PATCH 0079/1002] powerpc/85xx: Make eSDHC 1-bit only transfer mode
default for MPC8569E-MDS
For yet unknown reason 4-bit mode doesn't work on MPC8569E-MDS boards,
so make 1-bit mode default. When we resolve the issue, u-boot will
remove sdhci,1-bit-only property from the device tree, while SDHCI
will still work with older u-boots.

Commit 52da219e9664e537a745877b0efa7cf2b1ff2996 removed
the s3c_device_iis, but didn't replace it with anything
so a number of s3c24xx machines are currently failing
to build.
As a temporary fix, re-instate s3c_device_iis until a
proper replacement can be done for it.

Subject: [PATCH 0085/1002] [ARM] S3C: Fix S3C24XX build to not include s3c64xx
IIS devices
Commit 52da219e9664e537a745877b0efa7cf2b1ff2996 added IIS
platform devices, but these do not build on s3c24xx systems
and the file depends on SND_S3C24XX_SOC, which is selected
for all S3C64XX/S3C24XX systems.
As a quick fix, make the dev-audio.o file depends on
SND_S3C64XX_SOC_I2S instead.

all works for suspend/resume is done in bd2802_suspend and bd2802_suspend

Subject: [PATCH 0091/1002] leds: add the sysfs interface into the leds-bd2802
driver for changing wave pattern and led current.
Allow the user application to change the wave pattern and led current by
'wave_pattern' and 'rgb_current' sysfs files.

WARNING: drivers/leds/leds-gpio.o(.text+0x153): Section mismatch in reference from the function gpio_led_probe() to the function .devinit.text:create_gpio_led()
The function gpio_led_probe() references the function __devinit
create_gpio_led(). This is often because gpio_led_probe lacks a __devinit
annotation or the annotation of create_gpio_led is wrong.

Subject: [PATCH 0097/1002] leds: LED driver for National Semiconductor LP3944
Funlight Chip
LEDs driver for National Semiconductor LP3944 Funlight Chip
http://www.national.com/pf/LP/LP3944.html
This helper chip can drive up to 8 leds, with two programmable DIM
modes; it could even be used as a gpio expander but this driver assumes
it is used as a led controller.
The DIM modes are used to set _blink_ patterns for leds, the pattern is
specified supplying two parameters:
- period: from 0s to 1.6s
- duty cycle: percentage of the period the led is on, from 0 to 100
LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
leds, the camera flash light and the displays backlights.

+====================
+
+ * National Semiconductor LP3944 Fun-light Chip
+ Prefix: 'lp3944'
+ Addresses scanned: None (see the Notes section below)
+ Datasheet: Publicly available at the National Semiconductor website

+
+Description
+-----------
+The LP3944 is a helper chip that can drive up to 8 leds, with two programmable
+DIM modes; it could even be used as a gpio expander but this driver assumes it
+is used as a led controller.
+
+The DIM modes are used to set _blink_ patterns for leds, the pattern is
+specified supplying two parameters:
+ - period: from 0s to 1.6s
+ - duty cycle: percentage of the period the led is on, from 0 to 100
+
+Setting a led in DIM0 or DIM1 mode makes it blink according to the pattern.
+See the datasheet for details.
+
+LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
+leds, the camera flash light and the lcds power.
+
+
+Notes
+-----
+The chip is used mainly in embedded contexts, so this driver expects it is
+registered using the i2c_board_info mechanism.
+
+To register the chip at address 0x60 on adapter 0, set the platform data
+according to include/linux/leds-lp3944.h, set the i2c board info:
+
+ static struct i2c_board_info __initdata a910_i2c_board_info[] = {
+ {
+ I2C_BOARD_INFO("lp3944", 0x60),
+ .platform_data = &a910_lp3944_leds,
+ },
+ };
+
+and register it in the platform init function
+
+ i2c_register_board_info(0, a910_i2c_board_info,
+ ARRAY_SIZE(a910_i2c_board_info));

For one, it's a inefficient way to do it and requires led trigger support
to be compiled in.
But the real reason is that is produces a glitch on the LED. The GPIO is
allocate with the LED *off*, then *later* when the trigger runs it is
turned back on. If the LED was already on via the GPIO's reset default or
action of the firmware, this produces a glitch where the LED goes from on
to off to on. While normally this is fast enough that it wouldn't be
noticeable to a human observer, there are still serious problems.
One is that there may be something else on the GPIO line, like a hardware
alarm or watchdog, that is fast enough to notice the glitch.
Another is that the kernel may panic before the LED is turned back on, thus
hanging with the LED in the wrong state. This is not just speculation, but
actually happened to me with an embedded system that has an LED which
should turn off when the kernel finishes booting, which was left in the
incorrect state due to a bug in the OF LED binding code.
We also let GPIO LEDs get their initial value from whatever the current
state of the GPIO line is. On some systems the LEDs are put into some
state by the firmware or hardware before Linux boots, and it is desired to
have them keep this state which is otherwise unknown to Linux.
This requires that the underlying GPIO driver support reading the value of
output GPIOs. Some drivers support this and some do not.
The platform device binding gains a field in the platform data
"default_state" that controls this. There are three constants defined to
select from on, off, or keeping the current state. The OpenFirmware
binding uses a property named "default-state" that can be set to "on",
"off", or "keep". The default if the property isn't present is off.

Looks like I managed to mess up most shifts when converting from bitfields. :(
The patch below works on my Thinkpad T500 (as well as on my PowerBook,
where the previous change worked as well, maybe out of luck...). I'd
appreciate more testing and eyes looking over it though.

Subject: [PATCH 0110/1002] ide: fix handling of unexpected IRQs vs
request_irq()
Add ide_host_enable_irqs() helper and use it in ide_host_register()
before registering ports. Then remove no longer needed IRQ unmasking
from in init_irq().
This should fix the problem with "screaming" shared IRQ on the first
port (after request_irq() call while we have the unexpected IRQ pending
on the second port) which was uncovered by my rework of the serialized
interfaces support.

Subject: [PATCH 0111/1002] ide-cd: Don't warn on bogus block size unless it
actually matters.
Frans Pop reported that his CDROM drive reports a blocksize of 2352,
and this causes new warnings due to commit
e8e7b9eb11c34ee18bde8b7011af41938d1ad667 ("ide-cd: fix oops when using
growisofs").
What we're trying to do is make sure that "blocklen >> SECTOR_BITS"
is something the block layer won't choke on.
And for Frans' case "2352 >> SECTOR_BITS" is equal to
"2048 >> SECTOR_BITS", and thats "4".
So warning in this case gives no real benefit.

Subject: [PATCH 0112/1002] ide-cd: Improve "weird block size" error message
Currently the error gets repeated too frequently, for example each
time HAL polls the device when a disc is present. Avoid that by using
printk_once instead of printk.
Also join the error and corrective action messages into a single line.

Subject: [PATCH 0113/1002] ide: relax DMA info validity checking
There are some broken devices that report multiple DMA xfer modes
enabled at once (ATA spec doesn't allow it) but otherwise work fine
with DMA so just delete ide_id_dma_bug().
[ As discovered by detective work by Frans and Bart, due to how
handling of the ID block was handled before commit c419993
("ide-iops: only clear DMA words on setting DMA mode") this
check was always seeing zeros in the fields or other similar
garbage. Therefore this check wasn't actually checking anything.
Now that the tests actually check the real bits, all we see are
devices that trigger the check yet work perfectly fine, therefore
killing this useless check is the best thing to do. -DaveM ]

Subject: [PATCH 0117/1002] perf_counter, x86: Set global control MSR correctly
Previous code made an assumption that the power on value of global
control MSR has enabled all fixed and general purpose counters properly.
However, this is not the case for certain Intel processors, such as
Atom - and it might also be firmware dependent.
Each enable bit in IA32_PERF_GLOBAL_CTRL is AND'ed with the
enable bits for all privilege levels in the respective IA32_PERFEVTSELx
or IA32_PERF_FIXED_CTR_CTRL MSRs to start/stop the counting of
respective counters. Counting is enabled if the AND'ed results is true;
counting is disabled when the result is false.
The end result is that all fixed counters are always disabled on Atom
processors because the assumption is just invalid.
Fix this by not initializing the ctrl-mask out of the global MSR,
but setting it to perf_counter_mask.

Subject: [PATCH 0118/1002] tracing/events: Don't increment @pos in s_start()
While testing syscall tracepoints posted by Jason, I found 3 entries
were missing when reading available_events. The output size of
available_events is < 4 pages, which means we lost 1 entry per page.
The cause is, it's wrong to increment @pos in s_start().
Actually there's another bug here -- reading avaiable_events/set_events
can race with module unload:
# cat available_events |
s_start() |
s_stop() |
| # rmmod foo.ko
s_start() |
call = list_entry(m->private) |
@call might be freed and accessing it will lead to crash.

Subject: [PATCH 0122/1002] ftrace: Don't increment @pos in g_start()
It's wrong to increment @pos in g_start(). It causes some entries
lost when reading set_graph_function, if the output of the file
is larger than PAGE_SIZE.

Subject: [PATCH 0123/1002] ftrace: Don't manipulate @pos in t_start()
It's rather confusing that in t_start(), in some cases @pos is
incremented, and in some cases it's decremented and then incremented.
This patch rewrites t_start() in a much more general way.
Thus we fix a bug that if ftrace_filtered == 1, functions have tracer
hooks won't be printed, because the branch is always unreachable:
static void *t_start(...)
{
...
if (!p)
return t_hash_start(m, pos);
return p;
}
Before:
# echo 'sys_open' > /mnt/tracing/set_ftrace_filter
# echo 'sys_write:traceon:4' >> /mnt/tracing/set_ftrace_filter
sys_open
After:
# echo 'sys_open' > /mnt/tracing/set_ftrace_filter
# echo 'sys_write:traceon:4' >> /mnt/tracing/set_ftrace_filter
sys_open
sys_write:traceon:count=4

Subject: [PATCH 0124/1002] ftrace: Fix t_hash_start()
When the output of set_ftrace_filter is larger than PAGE_SIZE,
t_hash_start() will be called the 2nd time, and then we start
from the head of a hlist, which is wrong and causes some entries
to be outputed twice.
The worse is, if the hlist is large enough, reading set_ftrace_filter
won't stop but in a dead loop.

Subject: [PATCH 0125/1002] timer stats: Optimize by adding quick check to
avoid function calls
When the kernel is configured with CONFIG_TIMER_STATS but timer
stats are runtime disabled we still get calls to
__timer_stats_timer_set_start_info which initializes some
fields in the corresponding struct timer_list.
So add some quick checks in the the timer stats setup functions
to avoid function calls to __timer_stats_timer_set_start_info
when timer stats are disabled.
In an artificial workload that does nothing but playing ping
pong with a single tcp packet via loopback this decreases cpu
consumption by 1 - 1.5%.
This is part of a modified function trace output on SLES11:

Subject: [PATCH 0126/1002] osdblk: a Linux block device for OSD objects
Submitted driver exports a block device of the form /dev/osdblkX,
where X is a decimal number.
It does that by mounting a stacking block device on top
of an osd object. For example, if you create a 2G object
on an OSD device, you can then use this module to present
that 2G object as a Linux block device.
See inside patch for exact documentation.
[Sitting at linux-next helped fix proper Kconfig dependency
for this driver, thanks to Randy Dunlap]

+ Instructions for use
+ --------------------
+
+ 1) Map a Linux block device to an existing OSD object.
+
+ In this example, we will use partition id 1234, object id 5678,
+ OSD device /dev/osd1.
+
+ $ echo "1234 5678 /dev/osd1" > /sys/class/osdblk/add
+
+
+ 2) List all active blkdev<->object mappings.
+
+ In this example, we have performed step #1 twice, creating two blkdevs,
+ mapped to two separate OSD objects.
+
+ $ cat /sys/class/osdblk/list
+ 0 174 1234 5678 /dev/osd1
+ 1 179 1994 897123 /dev/osd0
+
+ The columns, in order, are:
+ - blkdev unique id
+ - blkdev assigned major
+ - OSD object partition id
+ - OSD object id
+ - OSD device
+
+
+ 3) Remove an active blkdev<->object mapping.
+
+ In this example, we remove the mapping with blkdev unique id 1.
+
+ $ echo 1 > /sys/class/osdblk/remove
+
+
+ NOTE: The actual creation and deletion of OSD objects is outside the scope
+ of this driver.

Subject: [PATCH 0127/1002] osdblk: Adjust queue limits to lower device's
limits
call blk_queue_stack_limits() to copy queue limits from
the underline osd scsi_device. This is absolutely needed
because osdblk cannot sleep when allocating a lower-request and
therefore cannot be bouncing.
TODO: Dynamic changes of limits to the lower device queue
will not reflect in the upper driver

number.
In 86ccf37c6acd74cf7e4b7751ee045de19943c5a0 the driver was modified
to deal with the removal of the pciirq argument to ide_pci_setup_ports().
But in the conversion only the first port's IRQ gets setup.
Inspired by a patch by Bartlomiej Zolnierkiewicz., and with help from
Alan Cox.

Subject: [PATCH 0131/1002] clocksource: sh_tmu: Make undefined TCOR behaviour
less undefined.
Avoid undocumented vague TMU behavior when zero value is set to TCOR.
This primarily fixes up issues encountered under qemu with a zero-length
period, while the hardware itself is fairly ambivalent one way or the
other.

Add a new flag to ad_spec struct so that the same hack can be used for
any other models (if any). This also allows other models to reuse the
auto-mute functions.

Subject: [PATCH 0135/1002] rcu: Mark Hierarchical RCU no longer experimental
Removes the warnings about Hierarchical RCU being experimental,
given that it has gone through almost six months of being the
default RCU in mainline for the x86 with very little trouble.
This makes hierarchical-RCU bootup look less scary.

Subject: [PATCH 0138/1002] x86: Fix uv bau sending buffer initialization
The initialization of the UV Broadcast Assist Unit's sending
buffers was making an invalid assumption about the
initialization of an MMR that defines its address.
The BIOS will not be providing that MMR. So
uv_activation_descriptor_init() should unconditionally set it.
Tested on UV simulator.

Thanks guys, these libraries are really useful. Special thanks

This patch has CIFS look for a '%' in an IPv6 address. If one is
present then it will try to treat that value as a numeric interface
index suitable for stuffing into the sin6_scope_id field.
This should allow people to mount servers on IPv6 link-local addresses.

Subject: [PATCH 0149/1002] [CIFS] cleanup asn handling for ntlmssp
Also removes obsolete distinction between rawntlmssp and ntlmssp (in asn/SPNEGO)
since as jra noted we can always send raw ntlmssp in session setup now.
remove check for experimental runtime flag (/proc/fs/cifs/Experimental) in
ntlmssp path.

Subject: [PATCH 0151/1002] ALSA: hda - Add pin-sense trigger when needed for
Realtek codecs
Realtek codecs require the pin-sense trigger call before actually
reading the pin-sense. Without this, the pin-detection might not be
done accurately.
This patch adds the pin-capability check and issues the trigger call
if required.

API to support 64-bit device size") has changed some structure values
to 64-bit and has not updated this debug message, since it's not built
by default.

Subject: [PATCH 0160/1002] ring-buffer: Make it generally available
In hunting down the cause for the hwlat_detector ring buffer spew in
my failed -next builds it became obvious that folks are now treating
ring_buffer as something that is generic independent of tracing and thus,
suitable for public driver consumption.
Given that there are only a few minor areas in ring_buffer that have any
reliance on CONFIG_TRACING or CONFIG_FUNCTION_TRACER, provide stubs for
those and make it generally available.

Subject: [PATCH 0161/1002] kmemleak: Allow the early log buffer to be
configurable.
(feature suggested by Sergey Senozhatsky)
Kmemleak needs to track all the memory allocations but some of these
happen before kmemleak is initialised. These are stored in an internal
buffer which may be exceeded in some kernel configurations. This patch
adds a configuration option with a default value of 400 and also removes
the stack dump when the early log buffer is exceeded.

Subject: [PATCH 0162/1002] perf record: Fix filemap pathname parsing in
/proc/pid/maps
Looking backward for the first space from the end of a line in
/proc/pid/maps does not find the start of the pathname of the mapped
file if it contains a space.
Since the only slashes we have in this file occur in the (absolute!)
pathname column of file mappings, looking for the first slash in a
line is a safe method to find the name.

Subject: [PATCH 0163/1002] Revert "veth: prevent oops caused by netdev
destructor"
This reverts commit ae0e8e82205c903978a79ebf5e31c670b61fa5b4.
This change had two problems:
1) Since it frees the stats in the drivers' close method, we
can OOPS in the transmit routine.
2) stats are no longer remembered across ifdown/ifup which
disagrees with how every other device operates.
Thanks to analysis and test patch from Serge E. Hallyn
and initial OOPS report by Sachin Sant.

Subject: [PATCH 0169/1002] futex: request only one page from get_user_pages()
Yanmin noticed that fault_in_user_writeable() requests 4 pages instead
of one.
That's the result of blindly trusting Linus' proposal :) I even looked
up the prototype to verify the correctness: the argument in question
is confusingly enough named "len" while in reality it means number of
pages.

Subject: [PATCH 0171/1002] [ARM] 5560/1: Avoid buffer overrun in case of an
invalid IRQ
handle_bad_irq() expects the IRQ number to be valid (used for statistics),
so it cannot be called with an illegal vector. The problem was reported
by a static analysis tool.
The change makes bad_irq_desc redundant, so delete it.

Subject: [PATCH 0172/1002] [ARM] 5565/2: Use PAGE_SIZE and RO_DATA() in link
script
Update the link script for ARM to use PAGE_SIZE instead of hard-
coded 4096. Also the old RODATA macro is deprecated
for the RO_DATA(PAGE_SIZE) macro. As a consequence the PAGE_SIZE
was changed from (1UL << PAGE_SHIFT) to (_AC(1,UL) << PAGE_SHIFT)
because the linker does not understand the "UL" suffix to numeric
constants.

Subject: [PATCH 0174/1002] nf_conntrack: Use rcu_barrier()
RCU barriers, rcu_barrier(), is inserted two places.
In nf_conntrack_expect.c nf_conntrack_expect_fini() before the
kmem_cache_destroy(). Firstly to make sure the callback to the
nf_ct_expect_free_rcu() code is still around. Secondly because I'm
unsure about the consequence of having in flight
nf_ct_expect_free_rcu/kmem_cache_free() calls while doing a
kmem_cache_destroy() slab destroy.
And in nf_conntrack_extend.c nf_ct_extend_unregister(), inorder to
wait for completion of callbacks to __nf_ct_ext_free_rcu(), which is
invoked by __nf_ct_ext_add(). It might be more efficient to call
rcu_barrier() in nf_conntrack_core.c nf_conntrack_cleanup_net(), but
thats make it more difficult to read the code (as the callback code
in located in nf_conntrack_extend.c).

Subject: [PATCH 0176/1002] [SCSI] ibmvscsi: Fix module load hang
Fixes a regression seen in the ibmvscsi driver when using the VSCSI
server in SLES 9 and SLES 10. The VSCSI server in these releases
has a bug in it in which it does not send responses to unknown MADs.
Check the OS Type field in the adapter info response and do not send
these unsupported commands when talking to an older server.

The shost sg tablesize is set to FNIC_MAX_SG_DESC_CNT and fnic uses
scsi_dma_map, so both BUG_ONs can be removed.
scsi_dma_map may return -ENOMEM, sg_count should be int to catch that.

Subject: [PATCH 0179/1002] [SCSI] zalon: fix oops on attach failure
I recently discovered on my zalon that if the attachment fails because
of a bus misconfiguration (I scrapped my HVD array, so the card is now
unterminated) then the system oopses. The reason is that if
ncr_attach() returns NULL (signalling failure) that NULL is passed by
the goto failed straight into ncr_detach() which oopses.
The fix is just to return -ENODEV in this case.

Subject: [PATCH 0180/1002] firewire: core: do not DMA-map stack addresses
The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet
payload buffers in firewire-core (payload of lock requests in the bus
manager work and in iso resource management) to slab-allocated memory.
There are a number on-stack buffers for quadlet write or quadlet read
requests in firewire-core and firewire-sbp2. These are harmless; they
are copied to/ from card driver internal DMA buffers since quadlet
payloads are inlined with packet headers.

Subject: [PATCH 0183/1002] clarify get_user_pages() prototype
Currently the 4th parameter of get_user_pages() is called len, but its
in pages, not bytes. Rename the thing to nr_pages to avoid future
confusion.

after open has failed.
This commit 10077d4a6674f535abdbe25cdecb1202af7948f1 has stopped
checking if there was a valid acm device associated to the tty, which is
not true right after open fails and tty subsystem tries to close the
device.
As an example, open fails with a non-existing device, when probe has
never been called, because the device has never been plugged. This is
common in systems with static modules and no udev.

Subject: [PATCH 0187/1002] cifs: Fix incorrect return code being printed in
cFYI messages
FreeXid() along with freeing Xid does add a cifsFYI debug message that
prints rc (return code) as well. In some code paths where we set/return
error code after calling FreeXid(), incorrect error code is being
printed when cifsFYI is enabled.
This could be misleading in few cases. For eg.
In cifs_open() if cifs_fill_filedata() returns a valid pointer to
cifsFileInfo, FreeXid() prints rc=-13 whereas 0 is actually being
returned. Fix this by setting rc before calling FreeXid().
Basically convert
FreeXid(xid); rc = -ERR;
return -ERR; => FreeXid(xid);
return rc;
[Note that Christoph would like to replace the GetXid/FreeXid
calls, which are primarily used for debugging. This seems
like a good longer term goal, but although there is an
alternative tracing facility, there are no examples yet
available that I know of that we can use (yet) to
convert this cifs function entry/exit logging, and for
creating an identifier that we can use to correlate
all dmesg log entries for a particular vfs operation
(ie identify all log entries for a particular vfs
request to cifs: e.g. a particular close or read or write
or byte range lock call ... and just using the thread id
is harder). Eventually when a replacement
for this is available (e.g. when NFS switches over and various
samples to look at in other file systems) we can remove the
GetXid/FreeXid macro but in the meantime multiple people
use this run time configurable logging all the time
for debugging, and Suresh's patch fixes a problem
which made it harder to notice some low
memory problems in the log so it is worthwhile
to fix this problem until a better logging
approach is able to be used]

Subject: [PATCH 0188/1002] nommu: provide follow_pfn().
With the introduction of follow_pfn() as an exported symbol, modules have
begun making use of it. Unfortunately this was not reflected on nommu at
the time, so the in-tree users have subsequently all blown up with link
errors there.
This provides a simple follow_pfn() that just returns addr >> PAGE_SHIFT,

checking within the vma, as the find_vma() case will already take care of
this.

Subject: [PATCH 0193/1002] perf_counter: Add PERF_EVENT_READ
Provide a read() like event which can be used to log the
counter value at specific sites such as child->parent
folding on exit.
In order to be useful, we log the counter parent ID, not the
actual counter ID, since userspace can only relate parent
IDs to perf_counter_attr constructs.

Subject: [PATCH 0194/1002] perf_counter: Implement more accurate per task
statistics
With the introduction of PERF_EVENT_READ we have the
possibility to provide accurate counter values for
individual tasks in a task hierarchy.
However, due to the lazy context switching used for similar
counter contexts our current per task counts are way off.
In order to maintain some of the lazy switch benefits we
don't disable it out-right, but simply iterate the active
counters and flip the values between the contexts.
This only reads the counters but does not need to reprogram
the full PMU.

Subject: [PATCH 0195/1002] perf_counter: Rework the sample ABI
The PERF_EVENT_READ implementation made me realize we don't
actually need the sample_type int the output sample, since
we already have that in the perf_counter_attr information.
Therefore, remove the PERF_EVENT_MISC_OVERFLOW bit and the
event->type overloading, and imply put counter overflow
samples in a PERF_EVENT_SAMPLE type.
This also fixes the issue that event->type was only 32-bit
and sample_type had 64 usable bits.

Subject: [PATCH 0199/1002] x86: Add sysctl to allow panic on IOCK NMI error
This patch introduces a new sysctl:
/proc/sys/kernel/panic_on_io_nmi
which defaults to 0 (off).
When enabled, the kernel panics when the kernel receives an NMI
caused by an IO error.
The IO error triggered NMI indicates a serious system
condition, which could result in IO data corruption. Rather
than contiuing, panicing and dumping might be a better choice,
so one can figure out what's causing the IO error.
This could be especially important to companies running IO
intensive applications where corruption must be avoided, e.g. a
bank's databases.
[ SuSE has been shipping it for a while, it was done at the
request of a large database vendor, for their users. ]

CONFIG_X86_64 was misspelled (wrong case), which caused the x86-64
kernel to advertise itself as more relocatable than it really is.
This could in theory cause boot failures once bootloaders start

order to resolve PMD_SHIFT. Also, correct a +1 which really should be
+ THREAD_ORDER.
This is a build error which was masked by a typoed #ifdef.

Subject: [PATCH 0208/1002] sparc: fix tftpboot.img build
Kjetil Oftedal mentioned that piggyback_32 was failing
when building a sparc image.
I tracked this down to the fact that the kernel no longer
provided an absolute symbol named "end".
Commit 86ed40bd6fe511d26bb8f3fa65a84cb65c235366 ("sparc: unify sections.h")
renamed end to _end but failed to update piggyback_32.

It turns out that $(obj)/image wasn't being generated which was causing the a.out conversion to be skipped and hence piggyback to be called with nonexistent files.

Subject: [PATCH 0216/1002] [CIFS] remove bkl usage from umount begin
The lock_kernel call moved into the fs for umount_begin
is not needed. This adds a check to make sure we don't
call umount_begin twice on the same fs.
umount_begin for cifs is probably not needed and
may eventually be able to be removed, but in
the meantime this smaller patch is safe and
gets rid of the bkl from this path which provides
some benefit.

Subject: [PATCH 0217/1002] [CIFS] remove unknown mount option warning message
Jeff's previous patch which removed the unneeded rw/ro
parsing can cause a minor warning in dmesg (about the
unknown rw or ro mount option) at mount time. This
patch makes cifs ignore them in kernel to remove the warning
(they are already handled in the mount helper and VFS).

Subject: [PATCH 0218/1002] eeepc-laptop: Register as a pci-hotplug device
The eee contains a logically (but not physically) hotpluggable PCIe slot.
Currently this is handled by adding or removing the PCI device in response
to rfkill events, but if a user has forced pciehp to bind to it (with the
force=1 argument) then both drivers will try to handle the event and
hilarity (in the form of oopses) will ensue. This can be avoided by having
eee-laptop register the slot as a hotplug slot. Only one of pciehp and
eee-laptop will successfully register this, avoiding the problem.

CMSG is an ACPI method used to find features available on
an Eee PC. But some features are never repported, even if present.
If the getter of a feature is present, this patch will set
the corresponding bit in cmsg.

Subject: [PATCH 0225/1002] ACPI: video: prevent NULL deref in
acpi_get_pci_dev()
ref: http://thread.gmane.org/gmane.linux.kernel/857228/focus=857468
When the ACPI video driver initializes, it does a namespace walk
looking for for supported devices. When we find an appropriate
handle, we walk up the ACPI tree looking for a PCI root bus, and
then walk back down the PCI bus, assuming that every device
inbetween is a P2P bridge.
This assumption is not correct, and is reported broken on at
least:
Dell Latitude E6400
ThinkPad X61
Dell XPS M1330
Add a NULL deref check to prevent boot panics.

Turning on SWIOTLB selects or enables PPC_NEED_DMA_SYNC_OPS, which means
we get the non empty versions of dma_sync_* in asm/dma-mapping.h
On my pseries machine the dma_ops have no such routines and we die with
a null pointer - this patch gets it booting, is there a more elegant way
to do it?

Subject: [PATCH 0227/1002] powerpc/mpic: Fix mapping of "DCR" based MPIC
variants
Commit 31207dab7d2e63795eb15823947bd2f7025b08e2
"Fix incorrect allocation of interrupt rev-map"
introduced a regression crashing on boot on machines using
a "DCR" based MPIC, such as the Cell blades.
The reason is that the irq host data structure is initialized
much later as a result of that patch, causing our calls to
mpic_map() do be done before we have a host setup.
Unfortunately, this breaks _mpic_map_dcr() which uses the
mpic->irqhost to get to the device node.
This fixes it by, instead, passing the device node explicitely
to mpic_map().

Subject: [PATCH 0229/1002] powerpc/warp: Platform fix for i2c change
A change to the i2c subsystem breaks the warp platform code. The patch
is cleaner anyway, the old way was a bit crufty.
For those with keen eyes, the gratuitous change in the string from
PIKA to Warp is just so the logs look a bit nicer. The following two
lines tend to be printed one after another.
Warp POST OK
Warp DTM thread running.
Yeah, this will be the third patch to warp.c submitted in this
release....
Cheers,
Sean
The i2c_client struct changed, breaking the code that looked for the ad7414
chip. Use the new of_find_i2c_device_by_node function added in 2.6.29.

Subject: [PATCH 0231/1002] powerpc/pmac: Fix issues with PowerMac "PowerSurge"
SMP
The old PowerSurge SMP (ie, dual or quad 604 machines) code has
numerous issues in modern world.
One is cpu_possible_map is set too late (the device-tree is bogus)
so we fail to allocate the interrupt stacks and crash. Another
problem is the fact the timebase is frozen by the bringup of the
second CPU so the delays in the generic code will hang, we need
to move some of the calling procedure to inside the powermac code.
This makes it boot again for me

For some reason we've had an explicit KERN_INFO for GPR dumps. With
recent changes we get output like:

The KERN_INFO is causing the <6>. Don't see any reason to keep it
around.

Subject: [PATCH 0235/1002] powerpc/pmac: Fix DMA ops for MacIO devices
The macio_dev's created to map devices inside the MacIO ASICs
don't have proper dma_ops. This causes crashes on some machines
since the SCSI code calls dma_map_* on our behalf using the
device we hang from.
This fixes it by copying the parent PCI device dma_ops into
the macio_dev when creating it.

Subject: [PATCH 0236/1002] powerpc: Map more memory early on 601 processors
The 32-bit kernel relies on some memory being mapped covering
the kernel text,data and bss at least, early during boot before
the full MMU setup is done. On 32-bit "classic" processors, this
is done using BAT registers.
On 601, the size of BATs is limited to 8M and we use 2 of them
for that initial mapping. This can become quite tight when enabling
features like lockdep, so let's use a 3rd one to bump that mapping
from 16M to 24M. We keep the 4th BAT free as it can be useful for
debugging early boot code to map things like serial ports.

Alright, I've reworked this now so that if we get one of these cases
where there's a bsr that's > 4k and < 64k on a 64k kernel we'll only
advertise that it is a 4k BSR to userspace. I think this is the best
solution since user programs are only supposed to look at sysfs to
determine how much can be mapped, and libbsr does this as well.
Please consider for 2.6.31 as a fix, thanks.

Subject: [PATCH 0239/1002] powerpc: Add irqtrace support for 32-bit powerpc
Based on initial work from: Dale Farnsworth <dale@farnsworth.org>
Add the low level irq tracing hooks for 32-bit powerpc needed
to enable full lockdep functionality.
The approach taken to deal with the code in entry_32.S is that
we don't trace all the transitions of MSR:EE when we just turn
it off to peek at TI_FLAGS without races. Only when we are
calling into C code or returning from exceptions with a state
that have changed from what lockdep thinks.
There's a little bugger though: If we take an exception that
keeps interrupts enabled (such as an alignment exception) while
interrupts are enabled, we will call trace_hardirqs_on() on the
way back spurriously. Not a big deal, but to get rid of it would
require remembering in pt_regs that the exception was one of the
type that kept interrupts enabled which we don't know at this
stage. (Well, we could test all cases for regs->trap but that
sucks too much).

Subject: [PATCH 0240/1002] powerpc/rtas: Turn rtas lock into a raw spinlock
RTAS currently uses a normal spinlock. However it can be called from
contexts where this is not necessarily a good idea. For example, it
can be called while syncing timebases, with the core timebase being
frozen. Unfortunately, that will deadlock in case of lock contention
when spinlock debugging is enabled as the spin lock debugging code
will try to use __delay() which ... relies on the timebase being
enabled.
Also RTAS can be used in some low level IRQ handling code path so it
may as well be a raw spinlock for -rt sake.

Subject: [PATCH 0241/1002] powerpc: Use one common impl. of RTAS timebase sync
and use raw spinlock
Several platforms use their own copy of what is essentially the same code,
using RTAS to synchronize the timebases when bringing up new CPUs. This
moves it all into a single common implementation and additionally
turns the spinlock into a raw spinlock since the former can rely on
the timebase not being frozen when spinlock debugging is enabled, and finally
masks interrupts while the timebase is disabled.

Subject: [PATCH 0245/1002] powerpc/mm: Fix potential access to freed pages
when using hugetlbfs
When using 64k page sizes, our PTE pages are split in two halves,
the second half containing the "extension" used to keep track of
individual 4k pages when not using HW 64k pages.
However, our page tables used for hugetlb have a slightly different
format and don't carry that "second half".
Our code that batched PTEs to be invalidated unconditionally reads
the "second half" (to put it into the batch), which means that when
called to invalidate hugetlb PTEs, it will access unrelated memory.
It breaks when CONFIG_DEBUG_PAGEALLOC is enabled.
This fixes it by only accessing the second half when the _PAGE_COMBO
bit is set in the first half, which indicates that we are dealing with
a "combo" page which represents 16x4k subpages. Anything else shouldn't
have this bit set and thus not require loading from the second half.

Subject: [PATCH 0251/1002] fix RCU-callback-after-kmem_cache_destroy problem
in sl[aou]b
Jesper noted that kmem_cache_destroy() invokes synchronize_rcu() rather than
rcu_barrier() in the SLAB_DESTROY_BY_RCU case, which could result in RCU
callbacks accessing a kmem_cache after it had been destroyed.

Subject: [PATCH 0253/1002] amd64_edac: check only ECC bit in
amd64_determine_edac_cap
Checking whether the machine is using ECC enabled DRAM is done through
testing the DimmEccEn bit in the DRAM Cfg Low register (F2x[1,0]90). Do
that instead of testing all bits from the DimmEccEn upwards.
Also, remove mci->edac_cap assignment and use value returned from
amd64_determine_edac_cap().

amd64_check_ecc_enabled() returns non-zero status when ECC

Subject: [PATCH 0256/1002] perf_counter tools: Prepare a small callchain
framework
We plan to display the callchains depending on some user-configurable
parameters.
To gather the callchains stats from the recorded stream in a fast way,
this patch introduces an ad hoc radix tree adapted for callchains and also
a rbtree to sort these callchains once we have gathered every events
from the stream.

Subject: [PATCH 0257/1002] perf report: Print sorted callchains per histogram
entries
Use the newly created callchains radix tree to gather the chains stats
from the recorded events and then print the callchains for all of them,
sorted by hits, using the "-c" parameter with perf report.
Example:
66.15% [k] atm_clip_exit
63.08%
0xffffffffffffff80
0xffffffff810196a8
0xffffffff810c14c8
0xffffffff8101a79c
0xffffffff810194f3
0xffffffff8106ab7f
0xffffffff8106abe5
0xffffffff8106acde
0xffffffff8100d94b
0xffffffff8153e7ea
[...]
1.54%
0xffffffffffffff80
0xffffffff810196a8
0xffffffff810c14c8
0xffffffff8101a79c
[...]

Subject: [PATCH 0263/1002] kmemleak: Do not trigger a scan when reading the
debug/kmemleak file
Since there is a kernel thread for automatically scanning the memory, it
makes sense for the debug/kmemleak file to only show its findings. This
patch also adds support for "echo scan > debug/kmemleak" to trigger an
intermediate memory scan and eliminates the kmemleak_mutex (scan_mutex
covers all the cases now).

Subject: [PATCH 0264/1002] kmemleak: Slightly change the policy on newly
allocated objects
Newly allocated objects are more likely to be reported as false
positives. Kmemleak ignores the reporting of objects younger than 5
seconds. However, this age was calculated after the memory scanning
completed which usually takes longer than 5 seconds. This patch
make the minimum object age calculation in relation to the start of the
memory scanning.

gracefully
There are some devices in the wild that clear the DRQ bit during the
last word of a packet command and therefore could use a "second chance"
for that last word of data to be xferred instead of simply failing the
request. Do that by attempting to suck in those last bytes in PIO mode.
In addition, the ATA_ERR bit has to be cleared for we cannot be sure the
data is valid otherwise.

Subject: [PATCH 0267/1002] tracing: Fix stack tracer sysctl handling
This made my machine completely frozen:
# echo 1 > /proc/sys/kernel/stack_tracer_enabled
# echo 2 > /proc/sys/kernel/stack_tracer_enabled
The cause is register_ftrace_function() was called twice.
Also fix ftrace_enabled sysctl, though seems nothing bad happened
as I tested it.

Have not verified that the possibility for new call_rcu() callbacks
has been disabled. As a hint for checking, the functions calling
call_rcu() (unx_destroy_cred and generic_destroy_cred) are
registered as crdestroy function pointer in struct rpc_credops.

RW_DATA_SECTION is defined to take 4 different alignment parameters,
while NOSAVE_DATA currently uses a fixed PAGE_SIZE alignment as noted
in the comments.
There are presently no in-tree users of this at present, and I just
stumbled across this while implementing the simplified script on a new
architecture port, which subsequently resulted in a syntax error.

This patch is preparation for replacing most uses of

to touch a lot of the kernel.
The long-term goal here is to be able to change the kernel's magic
section names to those that are compatible with -ffunction-sections
-fdata-sections. This requires renaming all magic sections with names
of the form ".data.foo".

Subject: [PATCH 0276/1002] asm-generic/vmlinux.lds.h: shuffle INIT_TASK* macro
names in vmlinux.lds.h
We recently added a INIT_TASK(align) in include/asm-generic/vmlinux.lds.h,
but there is already a macro INIT_TASK in include/linux/init_task.h, which
is quite confusing. We should switch the macro in the linker script to
INIT_TASK_DATA. (Sorry that I missed this in reviewing the patch). Since
the macros are new, there is only one user of the INIT_TASK in
vmlinux.lds.h, arch/mn10300/kernel/vmlinux.lds.S.
However, we are currently using INIT_TASK_DATA for laying down an entire
.data.init_task section. So rename that to INIT_TASK_DATA_SECTION.
I would be worried about changing the meaning of INIT_TASK_DATA, but the
old INIT_TASK_DATA implementation had no users, and in fact if anyone had
tried to use it, it would have failed to compile because it didn't pass
the alignment to the old INIT_TASK.

Subject: [PATCH 0280/1002] Kbuild: Disable the -Wformat-security gcc flag
Some distributions have enabled the gcc flag -Wformat-security by default.
This results in a number of warnings about format arguments to functions,
sometimes in cases where fixing the warning is not likely to actually fix a
bug. Instead of hand patching a dozens of places (possibly more) that produce
warnings that get ignored anyway we just turn off the flag in the Makefile.

Subject: [PATCH 0283/1002] inet: Call skb_orphan before tproxy activates
As transparent proxying looks up the socket early and assigns
it to the skb for later processing, we must drop any existing
socket ownership prior to that in order to distinguish between
the case where tproxy is active and where it is not.

Subject: [PATCH 0284/1002] gro: Flush GRO packets in napi_disable_pending path
When NAPI is disabled while we're in net_rx_action, we end up
calling __napi_complete without flushing GRO packets. This is
a bug as it would cause the GRO packets to linger, of course it
also literally BUGs to catch error like this :)
This patch changes it to napi_complete, with the obligatory IRQ
reenabling. This should be safe because we've only just disabled
IRQs and it does not materially affect the test conditions in
between.

Remove them as they are in essence dead code - as unlike upstream
Git, the perf tool is unlikely to be ported to Windows.

Subject: [PATCH 0288/1002] mtd: Use BLOCK_NIL consistently in NFTL/INFTL
Use BLOCK_NIL consistently rather than sometimes 0xffff and sometimes
BLOCK_NIL.
The semantic patch that finds this issue is below
(http://www.emn.fr/x-info/coccinelle/). On the other hand, the changes
were made by hand, in part because drivers/mtd/inftlcore.c contains dead
code that causes spatch to ignore a relevant function. Specifically, the
function INFTL_findwriteunit contains a do-while loop, but always takes a
return that leaves the loop on the first iteration.

Subject: [PATCH 0294/1002] [ARM] 5566/1: Remove at91_gpiolib_request
Remove at91_gpiolib_request. It returns -EPERM if a request pin is not
in GPIO mode, however we want to be able to gpio_request alternative
function pins to reserve them, and in some cases we need to be able to
use the gpiolib functions on alternative function pins.

management
Add the at91sam9g45 series support to the AT91 generic clock file.
This takes care of the particularities of the PMC for this series.
It also takes advantage of the management by functionalities of
those PLLs and clocks.

From 789b23bc40a67d9a19bedc2655c6bcab79bcabd8 Mon Sep 17 00:00:00 2001
From: Nicolas Ferre <nicolas.ferre@atmel.com>
Date: Fri, 26 Jun 2009 15:36:58 +0100
Subject: [PATCH 0297/1002] [ARM] 5572/1: at91: Support for at91sam9g45 series:
core chip & board support
Here are the at91 specific files dedicated to the at91sam9g45 series. They
mimic the traditional at91 way of managing chips & boards.
The first board that embeds at91sam9g45 chip is the AT91SAM9G45-EKES. In
the future, the main board for this 9g45 series will be the
AT91SAM9M10G45-EK (I choose this last name for the board file).
Simple drivers are enabled in _devices and board- files. Newer peripheral
support will be added in future patches.
Incuded peripherals support (for now):
- USART
- SPI
- Ethernet
- NAND flash
- LCD
- gpio/joystick/buttons
- leds and pwm

Subject: [PATCH 0298/1002] perf stat: Improve output
Increase size for event name to handle bigger names like
'L1-d$-prefetch-misses'
Changed scaled counters from percentage to a multiplicative
factor because the latter is more expressive.
Also aligned the scaling factor, otherwise sometimes it looks
like:
384 iTLB-load-misses (4.74x scaled)
452029 branch-loads (8.00x scaled)
5892 branch-load-misses (20.39x scaled)
972315 iTLB-loads (3.24x scaled)
Before:
150708 L1-d$-stores (scaled from 23.57%)
428804 L1-d$-prefetches (scaled from 23.47%)
314446 L1-d$-prefetch-misses (scaled from 23.42%)
252626137 L1-i$-loads (scaled from 23.24%)
5297550 dTLB-load-misses (scaled from 23.96%)
106992392 branch-loads (scaled from 23.67%)
5239561 branch-load-misses (scaled from 23.43%)
After:
1731713 L1-d$-loads ( 14.25x scaled)
44241 L1-d$-prefetches ( 3.88x scaled)
21076 L1-d$-prefetch-misses ( 3.40x scaled)
5789421 L1-i$-loads ( 3.78x scaled)
29645 dTLB-load-misses ( 2.95x scaled)
461474 branch-loads ( 6.52x scaled)
7493 branch-load-misses ( 26.57x scaled)

enabled
There is a bug when VLAN is configured on the cxgb3 interface, the iscsi
conn. would be denied with message "cxgb3i: NOT going through cxgbi device."
This patch adds code to get the real egress net_device when vlan is configured.

This reverts commit 95ee14e4379c5e19c0897c872350570402014742.
Mikael Petterson <mikepe@it.uu.se> reported that at least one of his
systems will not boot as a result. We have ruled out the detection
algorithm malfunctioning, so it is not a matter of producing the
incorrect bitmasks; rather, something in the application of them
fails.
Revert the commit until we can root cause and correct this problem.
-stable team: this means the underlying commit should be rejected.

make_all_cpus_request contains a race condition which can
trigger false request completed status, as follows:
CPU0 CPU1
if (test_and_set_bit(req,&vcpu->requests))
.... if (test_and_set_bit(req,&vcpu->requests))
.. return
proceed to smp_call_function_many(wait=1)
Use a spinlock to serialize concurrent CPUs.

Subject: [PATCH 0308/1002] KVM: s390: Allow stfle instruction in the guest
2.6.31-rc introduced an architecture level set checker based on facility
bits. e.g. if the kernel is compiled to run only on z9, several facility
bits are checked very early and the kernel refuses to boot if a z9 specific
facility is missing.
Until now kvm on s390 did not implement the store facility extended (STFLE)
instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not
boot in kvm. This patch implements stfle.
This patch should go in before 2.6.31.

Subject: [PATCH 0315/1002] integrity: add ima_counts_put (updated)
This patch fixes an imbalance message as reported by J.R. Okajima.
The IMA file counters are incremented in ima_path_check. If the
actual open fails, such as ETXTBSY, decrement the counters to
prevent unnecessary imbalance messages.

Subject: [PATCH 0316/1002] be2net: Fix to avoid a crash seen on PPC with LRO
and Jumbo frames.
While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames.
With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[].
Now we coalesce the frags from the same physical page into one slot in
skb_shinfo(skb)->frags[] and go to the next index when the frag is from
different physical page.
This patch is against the net-2.6 tree.

The Line In connector is set up as PIN_IN by default, using
VREF_HIZ. It is connected to both ADCs, so add it to both
input selectors.
Also add the ability to use the input mix (on a SoundBlaster
one would call this "What You Hear").

The keypad driver for the DM355 EVM got slightly broken as it merged,
since it moved from input/keyboard to input/misc and its Kconfig
symbol changed. This patch copes with the changed Kconfig symbol.

workqueue'
This reverts commit 0b346838c5862bfe911432956a106d602535d030.
This commit breaks GPIO debouncing by replacing the original mod_timer
with schedule_delayed_work in the interrupt handler. The latter does not
kick the timer further on GPIO line changes as it should to perform
debouncing.

Subject: [PATCH 0326/1002] Input: add support for generic GPIO-based matrix
keypad
Original patch by Marek Vasut, modified by Eric in:
1. use delayed work to simplify the debouncing
2. combine col_polarity/row_polarity into a single active_low field
3. use a generic bit array based XOR algorithm to detect key
press/release, which should make the column assertion time
shorter and code a bit cleaner
4. remove the ALT_FN handling, which is no way generic, the ALT_FN
key should be treated as no different from other keys, and
translation will be done by user space by commands like 'loadkeys'.
5. explicitly disable row IRQs and flush potential pending work,
and schedule an immediate scan after resuming as suggested
by Uli Luckas
6. incorporate review comments from many others
Patch tested on Littleton/PXA310 (though PXA310 has a dedicate keypad
controller, I have to configure those pins as generic GPIO to use this
driver, works quite well, though), and Sharp Zaurus model SL-C7x0
and SL-C1000.

Subject: [PATCH 0331/1002] ALSA: hda - Add missing initializations for ALC268
and ALC269
During the changes to clean up / fix the realtek codec initialization
routines in commit 4a79ba34cada6a5a4ee86ed53aa8a73ba1e6fc51,
I forgot to add the check for ALC268 and ALC269.
This resulted in the missing EAPD and COEF setup for these codecs.
This patch adds the missing checks for these codecs.

Subject: [PATCH 0335/1002] intel-iommu: Clean up identity mapping code, remove
CONFIG_DMAR_GFX_WA
There's no need for the GFX workaround now we have 'iommu=pt' for the
cases where people really care about performance. There's no need to
have a special case for just one type of device.
This also speeds up the iommu=pt path and reduces memory usage by
setting up the si_domain _once_ and then using it for all devices,
rather than giving each device its own private page tables.

Subject: [PATCH 0341/1002] netfilter: tcp conntrack: fix unacknowledged data
detection with NAT
When NAT helpers change the TCP packet size, the highest seen sequence
number needs to be corrected. This is currently only done upwards, when
the packet size is reduced the sequence number is unchanged. This causes
TCP conntrack to falsely detect unacknowledged data and decrease the
timeout.
Fix by updating the highest seen sequence number in both directions after
packet mangling.

Use unaligned address for domain->max_addr. That algorithm isn't ideal
anyway -- we should probably just look at the last iova in the tree.

Subject: [PATCH 0348/1002] netfilter: xtables: conntrack match revision 2
As reported by Philip, the UNTRACKED state bit does not fit within
the 8-bit state_mask member. Enlarge state_mask and give status_mask
a few more bits too.

Subject: [PATCH 0351/1002] intel-iommu: Introduce domain_pfn_mapping()
... and use it in the trivial cases; the other callers want individual
(and bisectable) attention, since I screwed them up the first time...
Make the BUG_ON() happen on too-large virtual address rather than
physical address, too. That's the one we care about.

for reserving PCI BARs
This is fairly broken anyway -- it doesn't take hotplug into account.
We should probably be checking page_is_ram() instead.

Subject: [PATCH 0359/1002] intel-iommu: Performance improvement for

It's a bit silly to repeatedly call domain_flush_cache() for each PTE
individually, as we clear it. Instead, batch them up and flush a whole
range at a time. We might as well refrain from recalculating the PTE
address from scratch each time round the loop too.

As with dma_pte_clear_range(), don't keep flushing a single PTE at a

using the helper functions to do all the masking.

Subject: [PATCH 0362/1002] fs: allow d_instantiate to be called with negative
parent dentry
The new fsnotify infrastructure (starting at 90586523) causes an oops in
spufs, where we populate a directory with files before instantiating the
directory itself. The new changes seem to have introduced an assumption
that a dentry's parent will be positive when instantiating.
This change makes it once again possible to d_instantiate a dentry
with a negative parent, and brings __fsnotify_d_instantiate() into
line with inotify_d_instantiate(), which already has this NULL check.

Subject: [PATCH 0370/1002] tty: Fix the leak in tty_ldisc_release
Currently we reinit the ldisc on final tty close which is what the old code
did to ensure that if the device retained its termios settings then it had the
right ldisc. tty_ldisc_reinit does that but also leaves us with the reset
ldisc reference which is then leaked.
At this point we know the port will be recycled so we can kill the ldisc
off completely rather than try and add another ldisc free up when the kref
count hits zero.
At this point it is safe to keep the ldisc closed as tty_ldisc waiting
methods are only used from the user side, and as the final close we are
the last such reference. Interrupt/driver side methods will always use the
non wait version and get back a NULL.
Found with kmemleak and investigated/identified by Catalin Marinas.

Subject: [PATCH 0372/1002] PCI MSI: Return if alloc_msi_entry for MSI-X failed
In current code it continues setup even if alloc_msi_entry() for MSI-X
is failed due to lack of memory. It means arch_setup_msi_irqs() might
be called with msi_desc entries less than its argument nvec.
At least x86's arch_setup_msi_irqs() uses list_for_each_entry() for
dev->msi_list that suspected to have entries same numbers as nvec, and
it doesn't check the number of allocated vectors and passed arg nvec.
Therefore it will result in success of pci_enable_msix(), with less
vectors allocated than requested.
This patch fixes the error route to return -ENOMEM, instead of continuing
the setup (proposed by Matthew Wilcox).
Note that there is no iounmap in msi_free_irqs() if no msi_disc is
allocated.

Subject: [PATCH 0377/1002] PCI: More PATA quirks for not entering D3
The ALi loses some state if it goes into D3. Unfortunately even with the
chipset documents I can't figure out how to restore some bits of it.
The VIA one saves/restores apparently fine but the ACPI _GTM methods break
on some platforms if we do this and this causes cable misdetections.
These are both effectively regressions as historically nothing matched the
devices and then decided not to bind to them. Nowdays something is binding
to all sorts of devices and a result they get dumped into D3.

Subject: [PATCH 0381/1002] PCI MSI: Fix restoration of MSI/MSI-X mask states
in suspend/resume
There are 2 problems on mask states in suspend/resume.
[1]:
It is better to restore the mask states of MSI/MSI-X to initial states
(MSI is unmasked, MSI-X is masked) when we release the device.
The pci_msi_shutdown() does the restoration of mask states for MSI,
while the msi_free_irqs() does it for MSI-X. In other words, in the
"disable" path both of MSI and MSI-X are handled, but in the "shutdown"
path only MSI is handled.
MSI:
pci_disable_msi()
=> pci_msi_shutdown()
[ mask states for MSI restored ]
=> msi_set_enable(dev, pos, 0);
=> msi_free_irqs()
MSI-X:
pci_disable_msix()
=> pci_msix_shutdown()
=> msix_set_enable(dev, 0);
=> msix_free_all_irqs
=> msi_free_irqs()
[ mask states for MSI-X restored ]
This patch moves the masking for MSI-X from msi_free_irqs() to
pci_msix_shutdown().
This change has some positive side effects:
- It prevents OS from touching mask states before reading preserved
bits in the register, which can be happen if msi_free_irqs() is
called from error path in msix_capability_init().
- It also prevents touching the register after turning off MSI-X in
"disable" path, which can be a problem on some devices.
[2]:
We have cache of the mask state in msi_desc, which is automatically
updated when msi/msix_mask_irq() is called. This cached states are
used for the resume.
But since what need to be restored in the resume is the states before
the shutdown on the suspend, calling msi/msix_mask_irq() from
pci_msi/msix_shutdown() is not appropriate.
This patch introduces __msi/msix_mask_irq() that do mask as same
as msi/msix_mask_irq() but does not update cached state, for use
in pci_msi/msix_shutdown().
[updated: get rid of msi/msix_mask_irq_nocache() (proposed by Matthew Wilcox)]

Subject: [PATCH 0383/1002] perf_counter tools: Reduce perf stat measurement
overhead/skew
Vince Weaver reported a 'perf stat' measurement overhead in the
count of retired instructions, which can amount to a +6000
instructions inflated count in the reported count.
At present, perf stat creates its counters on the perf process. Thus
the counters count the fork and various other activity in both the
parent and child, such as the resolver overhead for resolving PLT
entries for any libc functions that haven't been called before, such
as execvp.
This reduces the overhead by creating the counters on the child process
after the fork, using a couple of pipes to synchronize so that the
child process waits until the parent has created the counters before
doing the exec. To eliminate the PLT resolution overhead on calling
execvp, this does a dummy execvp first which will always fail.
With this, the overhead of executing a program goes down from over
4800 instructions to about 90 instructions on powerpc (32-bit).
This was measured with a statically-linked program written in
assembler which only does the 3 instructions needed to call _exit(0).
Before:
$ perf stat -e 0:1:u ./three
Performance counter stats for './three':
4858 instructions
0.001274523 seconds time elapsed
After:
$ perf stat -e 0:1:u ./three
Performance counter stats for './three':
92 instructions
0.000468153 seconds time elapsed

Subject: [PATCH 0384/1002] ide: fix resume for CONFIG_BLK_DEV_IDEACPI=y
commit 2f0d0fd2a605666d38e290c5c0d2907484352dc4 ("ide-acpi: cleanup
do_drive_get_GTF()") didn't account for the lack of hwif->acpidata
check in generic_ide_suspend() [ indirect user of do_drive_get_GTF()
through ide_acpi_exec_tfs() ] resulting in broken resume when ACPI
support is enabled but ACPI data is unavailable.
Fix it by adding ide_port_acpi() helper for checking if port needs
ACPI handling and cleaning generic_ide_{suspend,resume}() to use it
instead of hiding hwif->acpidata and ide_noacpi checks in IDE ACPI
helpers (this should help in preventing similar bugs in the future).
While at it:
- kill superfluous debugging printks in ide_acpi_{get,push}_timing()

Subject: [PATCH 0385/1002] ide: memory overrun in ide_get_identity_ioctl() on
big endian machines using ioctl HDIO_OBSOLETE_IDENTITY
This patch fixes a memory overrun in function ide_get_identity_ioctl() which
chooses the size of a memory buffer depending on the ioctl command that led
to the function call, however, passes that buffer to a function which needs the
buffer size to be always chosen unconditionally.
Due to conditional compilation the memory overrun can only happen on big endian
machines. The error can be triggered using ioctl HDIO_OBSOLETE_IDENTITY. Usage
of ioctl HDIO_GET_IDENTITY is safe.

Subject: [PATCH 0386/1002] tcp: Stop non-TSO packets morphing into TSO
If a socket starts out on a non-TSO route, and then switches to
a TSO route, then the tail on the tx queue can morph into a TSO
packet, causing mischief because the rest of the stack does not
expect a partially linear TSO packet.
This patch fixes this by ensuring that skb->ip_summed is set to
CHECKSUM_PARTIAL before declaring a packet as TSO.

Subject: [PATCH 0387/1002] tcp: Do not tack on TSO data to non-TSO packet
If a socket starts out on a non-TSO route, and then switches to
a TSO route, then we will tack on data to the tail of the tx queue
even if it started out life as non-TSO. This is suboptimal because
all of it will then be copied and checksummed unnecessarily.
This patch fixes this by ensuring that skb->ip_summed is set to
CHECKSUM_PARTIAL before appending extra data beyond the MSS.

number of cache flushes like domain_pfn_mapping() does, and gives a huge

_entire_ range is within the range we're intending to clear. The
early-termination condition was right, but not the loop.

ALSA SoC drivers should be specify SND_SOC_AC97_BUS instead, not AC97_BUS.
Without SND_SOC_AC97_BUS defined, an AC97 device will not get correctly
registered on the AC97 bus, which prevents thinks like the WM9712
touchscreen driver from getting probed.
Tested against 2.6.31-rc1.

Subject: [PATCH 0398/1002] ASoC: OMAP: fix OMAP1510 broken PCM pointer
callback
This patch tries to work around the problem of broken OMAP1510 PCM playback
pointer calculation by replacing DMA function call that incorrectly tries to
read the value form DMA hardware with a value computed locally from an
already maintained variable omap_runtime_data.period_index.
Tested on OMAP5910 based Amstrad Delta (E3) using work in progress ASoC
driver.
Based on linux-2.6-asoc.git v2.6.31-rc1.

This provides a way to mark a counter to be enabled on the next

launches it.
This also changes the perf stat command to use this new

Subject: [PATCH 0402/1002] perf_counter tools: Adjust only prelinked symbol's
addresses
I.e. we can't handle these two kinds of files in the same way:
1) prelinked system library:
[acme@doppio pahole]$ readelf -s /usr/lib64/libdw-0.141.so | egrep 'FUNC.+GLOBAL.+dwfl_report_elf'
278: 00000030450105a0 261 FUNC GLOBAL DEFAULT 12 dwfl_report_elf@@ELFUTILS_0.122
2) not prelinked library with debug information from a -debuginfo package:
[acme@doppio pahole]$ readelf -s /usr/lib/debug/usr/lib64/libdw-0.141.so.debug | egrep 'FUNC.+GLOBAL.+dwfl_report_elf'
629: 00000000000105a0 261 FUNC GLOBAL DEFAULT 12 dwfl_report_elf
[acme@doppio pahole]$
Now the numbers I got for a pahole perf run are in line with
the numbers I get from oprofile.

Subject: [PATCH 0403/1002] fuse: fix return value of fuse_dev_write()
On 64 bit systems -- where sizeof(ssize_t) > sizeof(int) -- the following test
exposes a bug due to a non-careful return of an int or unsigned value:
implement a FUSE filesystem which sends an unsolicited notification to
the kernel with invalid opcode. The respective write to /dev/fuse
will return (1 << 32) - EINVAL with errno == 0 instead of -1 with
errno == EINVAL.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch lets filesystems handle masking the file mode on creation.
This is needed if filesystem is using ACLs.
- The CREATE, MKDIR and MKNOD requests are extended with a "umask"
parameter.
- A new FUSE_DONT_MASK flag is added to the INIT request/reply. With
this the filesystem may request that the create mode is not masked.

Subject: [PATCH 0406/1002] fuse: invalidation reverse calls
Add notification messages that allow the filesystem to invalidate VFS
caches.
Two notifications are added:
1) inode invalidation
- invalidate cached attributes
- invalidate a range of pages in the page cache (this is optional)
2) dentry invalidation
- try to invalidate a subtree in the dentry cache
Care must be taken while accessing the 'struct super_block' for the
mount, as it can go away while an invalidation is in progress. To
prevent this, introduce a rw-semaphore, that is taken for read during
the invalidation and taken for write in the ->kill_sb callback.

Subject: [PATCH 0407/1002] bnx2x: Fix the behavior of ethtool when ONBOOT=no
This is the same fix as commit
7959ea254ed18faee41160b1c50b3c9664735967 ("bnx2: Fix the behavior of
ethtool when ONBOOT=no"), but for bnx2x:
--------------------
When configure in ifcfg-eth* is ONBOOT=no,
the behavior of ethtool command is wrong.
# grep ONBOOT /etc/sysconfig/network-scripts/ifcfg-eth2
ONBOOT=no
# ethtool eth2 | tail -n1
Link detected: yes
I think "Link detected" should be "no".

Subject: [PATCH 0414/1002] [IA64] address compiler warnings
perfmon.c/salinfo.c
perfmon.c has a dubious cast directly from "int" to "void *". Add
an intermediate cast to "long" to keep gcc happy.
salinfo.c uses "down_trylock()" in a highly creative way (explained
in the comments in the file) ... but it does kick out this warning:
arch/ia64/kernel/salinfo.c:195: warning: ignoring return value of 'down_trylock'
which people occasionally try to "fix" in ways that do not work. Use some
casts to keep gcc quiet.

Noticed the zero-sized function symbol while looking at 'perf' profiles,
it causes the profiler to display those addresses in hexa.
Turns out that this was wrong/bogus for an eternity.

Subject: [PATCH 0419/1002] perf report: Add --symbols parameter
So that we can filter by symbol name.
The 'pfunct' utility in the 'dwarves' package can be used to
create a file with the functions one wants.
Example:
[acme@doppio pahole]$ pfunct /usr/lib/debug/usr/lib64/libdw-0.141.so.debug | grep dwarf > /tmp/dwarf.symbols
[acme@doppio pahole]$ wc -l /tmp/dwarf.symbols
93 /tmp/dwarf.symbols
[acme@doppio pahole]$ head -3 /tmp/dwarf.symbols
dwfl_addrdwarf
dwfl_module_getdwarf
dwfl_getdwarf
[acme@doppio pahole]$ perf report --sort comm,dso,symbol --comms pahole --dsos /usr/lib64/libdw-0.141.so --symbols file:///tmp/dwarf.symbols
33.99% pahole /usr/lib64/libdw-0.141.so [.] dwarf_tag
29.07% pahole /usr/lib64/libdw-0.141.so [.] dwarf_decl_file

Subject: [PATCH 0420/1002] x86: Fix fixmap ordering
The merge of the 32- and 64-bit fixmap headers made a latent
bug on x86-64 a real one: with the right config settings
it is possible for FIX_OHCI1394_BASE to overlap the FIX_BTMAP_*
range.

Subject: [PATCH 0429/1002] md: avoid dereferencing NULL pointer when accessing
suspend_* sysfs attributes.
If we try to modify one of the md/ sysfs files
suspend_lo or suspend_hi
when the array is not active, we dereference a NULL.
Protect against that.

Subject: [PATCH 0430/1002] eventfd: revised interface and cleanups
Change the eventfd interface to de-couple the eventfd memory context, from
the file pointer instance.
Without such change, there is no clean way to racely free handle the
POLLHUP event sent when the last instance of the file* goes away. Also,
now the internal eventfd APIs are using the eventfd context instead of the
file*.
This patch is required by KVM's IRQfd code, which is still under
development.

Subject: [PATCH 0431/1002] gcov: fix __ctors_start alignment
The ctors section for each object file is eight byte aligned (on 64 bit).
However the __ctors_start symbol starts at an arbitrary address dependent
on the size of the previous sections.
Therefore the linker may add some zeroes after __ctors_start to make sure
the ctors contents are properly aligned. However the extra zeroes at the
beginning aren't expected by the code. When walking the functions
pointers contained in there and extra zeroes are added this may result in
random jumps. So make sure that the __ctors_start symbol is always
aligned as well.
Fixes this crash on an allyesconfig on s390:

Subject: [PATCH 0433/1002] fbdev: work around old compiler bug
When building with a 4.1.x compiler on powerpc64 (at least) we get this
error:
drivers/video/logo/logo_linux_mono.c:81: error: logo_linux_mono causes a section type conflict
This was introduced by commit ae52bb2384f721562f15f719de1acb8e934733cb
("fbdev: move logo externs to header file"). This is a partial revert of
that commit sufficient to not hit the compiler bug.
Also convert _clut arrays from __initconst to __initdata.
Sam said:
Al analysed this some time ago. When we say something is const then
_sometimes_ gcc annotate the section as const(?) - sometimes not. So if
we have two variables/functions annotated __*const and gcc decides to
annotate the section const only in one case we get a section type
conflict.

Subject: [PATCH 0434/1002] alpha: fix percpu build breakage
alpha percpu access requires custom SHIFT_PERCPU_PTR() definition for
modules to work around addressing range limitation. This is done via
generating inline assembly using C preprocessing which forces the
assembler to generate external reference. This happens behind the
compiler's back and makes the compiler think that static percpu variables
in modules are unused.
This used to be worked around by using __unused attribute for percpu
variables which prevent the compiler from omitting the variable; however,
recent declare/definition attribute unification change broke this as
__used can't be used for declaration. Also, in the process,
PER_CPU_ATTRIBUTES definition in alpha percpu.h got broken.
This patch adds PER_CPU_DEF_ATTRIBUTES which is only used for definitions
and make alpha use it to add __used for percpu variables in modules. This
also fixes the PER_CPU_ATTRIBUTES double definition bug.

Subject: [PATCH 0438/1002] elf: limit max map count to safe value
With ELF, at generating coredump, some more headers other than used
vmas are added.
When max_map_count == 65536, a core generated by following kinds of
code can be unreadable because the number of ELF's program header is
written in 16bit in Ehdr (please see elf.h) and the number overflows.
==
... = mmap(); (munmap, mprotect, etc...)
if (failed)
abort();
==
This can happen in mmap/munmap/mprotect/etc...which calls split_vma().
I think 65536 is not safe as _default_ and reduce it to 65530 is good
for avoiding unexpected corrupted core.
Anyway, max_map_count can be enlarged by sysctl if a user is brave..

Subject: [PATCH 0439/1002] ext2: return -EIO not -ESTALE on directory
traversal through deleted inode
ext2_iget() returns -ESTALE if invoked on a deleted inode, in order to
report errors to NFS properly. However, in ext[234]_lookup(), this
-ESTALE can be propagated to userspace if the filesystem is corrupted such
that a directory entry references a deleted inode. This leads to a
misleading error message - "Stale NFS file handle" - and confusion on the
part of the admin.
The bug can be easily reproduced by creating a new filesystem, making a
link to an unused inode using debugfs, then mounting and attempting to ls
-l said link.
This patch thus changes ext2_lookup to return -EIO if it receives -ESTALE
from ext2_iget(), as ext2 does for other filesystem metadata corruption;
and also invokes the appropriate ext*_error functions when this case is
detected.

Subject: [PATCH 0441/1002] spi: new spi->mode bits
Add two new spi_device.mode bits to accomodate more protocol options, and
pass them through to usermode drivers:
* SPI_NO_CS ... a second 3-wire variant, where the chipselect
line is removed instead of a data line; transfers are still
full duplex.
This obviously has STRONG protocol implications since the
chipselect transitions can't be used to synchronize state
transitions with the SPI master.
* SPI_READY ... defines open drain signal that's pulled low
to pause the clock. This defines a 5-wire variant (normal
4-wire SPI plus READY) and two 4-wire variants (READY plus
each of the 3-wire flavors).
Such hardware flow control can be a big win. There are ADC
converters and flash chips that expose READY signals, but not
many host controllers support it today.
The spi_bitbang code should be changed to use SPI_NO_CS instead of its
current nonportable hack. That's a mode most hardware can easily support
(unlike SPI_READY).

Add a new spi_master.flags word listing constraints relevant to that
controller. Define the first constraint bit: a half duplex restriction.
Include that constraint in the OMAP1 MicroWire controller driver.
Have the mmc_spi host be the first customer of this flag. Its coding
relies heavily on full duplex transfers, so it must fail when the
underlying controller driver won't perform them.
(The spi_write_then_read routine could use it too: use the
temporarily-withdrawn full-duplex speedup unless this flag is set, in
which case the existing code applies. Similarly, any spi_master
implementing only SPI_3WIRE should set the flag.)

Subject: [PATCH 0443/1002] fbdev: add mutex for fb_mmap locking
Add a mutex to avoid a circular locking problem between the mm layer
semaphore and fbdev ioctl mutex through the fb_mmap() call.
Also, add mutex to all places where smem_start and smem_len fields change
so the mutex inside the fb_mmap() is actually used. Changing of these
fields before calling the framebuffer_register() are not mutexed.
This is 2.6.31 material. It removes one lockdep (fb_mmap() and
register_framebuffer()) but there is still another one (fb_release() and
register_framebuffer()). It also cleans up handling of the smem_start and
smem_len fields used by mutexed section of the fb_mmap().

From 529ba0d9669386157457a1cb96294d2fe79b3f88 Mon Sep 17 00:00:00 2001
From: David Brownell <dbrownell@users.sourceforge.net>
Date: Tue, 30 Jun 2009 11:41:30 -0700
Subject: [PATCH 0444/1002] spi: bitbang bugfix in message setup
Bugfix to spi_bitbang infrastructure: make sure to always set transfer
parameters on the first pass through the message's per-transfer loop.
This can matter with drivers that replace the per-word or per-buffer
transfer primitives, on busses with multiple SPI devices.
Previously, this could have started messages using the settings left after
previous messages. The problem was observed when a high speed chip
(m25p80 type flash) was running very slowly because a low speed device
(avr8 microcontroller) had previously used the bus. Similar faults could
have driven the low speed device too fast, or used an unexpected word
size.

Subject: [PATCH 0448/1002] mm: prevent balance_dirty_pages() from doing too
much work
balance_dirty_pages can overreact and move all of the dirty pages to
writeback unnecessarily.
balance_dirty_pages makes its decision to throttle based on the number of
dirty plus writeback pages that are over the calculated limit,so it will
continue to move pages even when there are plenty of pages in writeback
and less than the threshold still dirty.
This allows it to overshoot its limits and move all the dirty pages to
writeback while waiting for the drives to catch up and empty the writeback
list.
A simple fio test easily demonstrates this problem.
fio --name=f1 --directory=/disk1 --size=2G -rw=write --name=f2 --directory=/disk2 --size=1G --rw=write --startdelay=10
This is the simplest fix I could find, but I'm not entirely sure that it
alone will be enough for all cases. But it certainly is an improvement on
my desktop machine writing to 2 disks.
Do we need something more for machines with large arrays where
bdi_threshold * number_of_drives is greater than the dirty_ratio ?

|
| page-allocator: clear N_HIGH_MEMORY map before we set it again
|
| SRAT tables may contains nodes of very small size. The arch code may
| decide to not activate such a node. However, currently the early boot
| code sets N_HIGH_MEMORY for such nodes. These nodes therefore seem to be
| active although these nodes have no present pages.
|
| For 64bit N_HIGH_MEMORY == N_NORMAL_MEMORY, so that works for 64 bit too
unintentionally and incorrectly clears the cpuset.mems cgroup attribute on
an i386 kvm guest, meaning that cpuset.mems can not be used.
Fix this by only clearing node_states[N_NORMAL_MEMORY] for 64bit only.
and need to do save/restore for that in find_zone_movable_pfn

Subject: [PATCH 0454/1002] atyfb: fix alignment for block writes
Block writes require 64 byte alignment. Since block writes could be used
with SGRAM or WRAM also refine the memory type detection to check for
either type before deciding to use the 64 byte alignment.

Subject: [PATCH 0455/1002] bfin: delay IRQ registration until driver is ready
Make sure we do not actually request the RTC IRQ until the device driver
is fully ready to handle and process any interrupt. This way a spurious
interrupt won't crash the system (which may happen if the bootloader was
poking the RTC right before booting Linux).

Subject: [PATCH 0460/1002] md: fix error path when duplicate name is found on
md device creation.
When an md device is created by name (rather than number) we need to
check that the name is not already in use. If this check finds a
duplicate, we return an error without dropping the lock or freeing
the newly create mddev.
This patch fixes that.

Subject: [PATCH 0461/1002] md: tidy up error paths in md_alloc
As the recent bug in md_alloc showed, having a single exit path for
unlocking and putting is a good idea. So restructure md_alloc to have
a single mutex_unlock and mddev_put, and use gotos where necessary.

Subject: [PATCH 0472/1002] ixgbe: fix unmap length bug
This patch addresses three WARN_ON statements from DMA-API debug code
ixgbe is mapping more than it unmaps, reduce the length of the map call and
remove the "used once" local variable.
found by Joerg Roedel <joerg.roedel@amd.com> in 2.6.30, so is a candidate
for -stable.
in addition, fix missing ->dma = 0 after unmap to prevent double free with
pci_unmap_single
and lastly, don't unmap (half) pages that aren't mapped.

PCI drivers that implement the io_error_detected callback
should return PCI_ERS_RESULT_DISCONNECT if the state
passed in is pci_channel_io_perm_failure. This state is
not checked in many of the network drivers.
The patch fixes the omission in the e1000 driver.

Subject: [PATCH 0478/1002] Revert "ipv4: arp announce, arp_proxy and windows
ip conflict verification"
This reverts commit 73ce7b01b4496a5fbf9caf63033c874be692333f.
After discovering that we don't listen to gratuitious arps in 2.6.30
I tracked the failure down to this commit.
The patch makes absolutely no sense. RFC2131 RFC3927 and RFC5227.
are all in agreement that an arp request with sip == 0 should be used
for the probe (to prevent learning) and an arp request with sip == tip
should be used for the gratitous announcement that people can learn
from.
It appears the author of the broken patch got those two cases confused
and modified the code to drop all gratuitous arp traffic. Ouch!

Subject: [PATCH 0479/1002] md/raid5: suspend shouldn't affect read requests.
md allows write to regions on an array to be suspended temporarily.
This allows user-space to participate is aspects of reshape.
In particular, data can be copied with not risk of a race.
We should not be blocking read requests though, so don't.

Subject: [PATCH 0480/1002] md: use interruptible wait when duration is
controlled by userspace.
User space can set various limits on an md array so that resync waits
when it gets to a certain point, or so that I/O is blocked for a short
while.
When md is waiting against one of these limit, it should use an
interruptible wait so as not to add to the load average, and so are
not to trigger a warning if the wait goes on for too long.

This fixes "memchunk" kernel command line selection

With this patch applied use "memchunk.ceu0=1m" or
"memchunk.ceu1=1m" on kernel command line to override
physically memory size to one meg for CEU0 or CEU1.

Subject: [PATCH 0486/1002] perf_counter tools: Various fixes for callchains
The symbol resolving has of course revealed some bugs in the
callchain tree handling. This patch fixes some of them,
including:
- inherit the children from the parents while splitting a node
- fix list range moving
- fix indexes setting in callchains
- create a child on the current node if the path doesn't match in
the existent children (was only done on the root)
- compare using symbols when possible so that we can match a function
using any ip inside by referring to its start address.
The practical effects are:
- remove double callchains
- fix upside down or any random order of callchains
- fix wrong paths
- fix bad hits and percentage accounts

Subject: [PATCH 0488/1002] perf_counter tools: Rework event string
parsing/syntax
This reworks the parser for event descriptors to make it more
consistent in what it accepts. It is now structured as a
recursive descent parser for the following grammar:
events ::= event ( ("," | space) space* event )*
event ::= ( raw_event | numeric_event | symbolic_event |
generic_hw_event ) [ event_modifier ]
raw_event ::= "r" hex_number
numeric_event ::= number ":" number
number ::= decimal_number | "0x" hex_number | "0" octal_number
symbolic_event ::= string_from_event_symbols_array
generic_hw_event::= cache_type ( "-" ( cache_op | cache_result ) )*
event_modifier ::= ":" ( "u" | "k" | "h" )+
with the extra restriction that you can have at most one
cache_op and at most one cache_result.
We pass the current string pointer by reference (i.e. as a
const char **) to the various parsing functions so that they
can advance the pointer to indicate how much they consumed.
They return 0 if they didn't recognize the thing at the pointer
or 1 if they did (and advance the pointer past it).
This also fixes parse_aliases to take the longest matching
alias from the table, not the first one. Otherwise "l1-data"
would match the "l1-d" alias and the "ata" would not be
consumed.
This allows event modifiers indicating what processor modes to
count in to be applied to any event, not just numeric events,
and adds a ":h" modifier to indicate counting in hypervisor
mode. Specifying ":u" now sets both exclude_kernel and
exclude_hv, and so on. Multiple modes can be specified, e.g.
":uk" will count in user or hypervisor mode (i.e. only
exclude_kernel will be set).

Subject: [PATCH 0489/1002] kprobes: No need to unlock kprobe_insn_mutex
Remove needless kprobe_insn_mutex unlocking during safety check
in garbage collection, because if someone releases a dirty slot
during safety check (which ensures other cpus doesn't execute
all dirty slots), the safety check must be fail. So, we need to
hold the mutex while checking safety.

Subject: [PATCH 0492/1002] cfq-iosched: get rid of the need for __GFP_NOFAIL
in cfq_find_alloc_queue()
Setup an emergency fallback cfqq that we allocate at IO scheduler init
time. If the slab allocation fails in cfq_find_alloc_queue(), we'll just
punt IO to that cfqq instead. This ensures that cfq_find_alloc_queue()
never fails without having to ensure free memory.
On cfqq lookup, always try to allocate a new cfqq if the given cfq io
context has the oom_cfqq assigned. This ensures that we only temporarily
punt to this shared queue.

Subject: [PATCH 0493/1002] block: Create bip slabs with embedded integrity
vectors
This patch restores stacking ability to the block layer integrity
infrastructure by creating a set of dedicated bip slabs. Each bip slab
has an embedded bio_vec array at the end. This cuts down on memory
allocations and also simplifies the code compared to the original bvec
version. Only the largest bip slab is backed by a mempool. The pool is
contained in the bio_set so stacking drivers can ensure forward
progress.

From 018e0446890661504783f92388ecce7138c1566d Mon Sep 17 00:00:00 2001
From: Jens Axboe <jens.axboe@oracle.com>
Date: Fri, 26 Jun 2009 16:27:10 +0200
Subject: [PATCH 0494/1002] block: get rid of queue-private command filter
The initial patches to support this through sysfs export were broken
and have been if 0'ed out in any release. So lets just kill the code
and reclaim some space in struct request_queue, if anyone would later
like to fixup the sysfs bits, the git history can easily restore
the removed bits.

Subject: [PATCH 0495/1002] blocK: Restore barrier support for md and probably
other virtual devices.
The next_ordered flag is only meaningful for devices that use __make_request.
So move the test against next_ordered out of generic code and in to
__make_request
Since this test was added, barriers have not worked on md or any
devices that don't use __make_request and so don't bother to set
next_ordered. (dm explicitly sets something other than
QUEUE_ORDERED_NONE since
commit 99360b4c18f7675b50d283301d46d755affe75fd
but notes in the comments that it is otherwise meaningless).

Therefore, we must not use the bootmem allocator in xen_init_IRQ().
Fixes the following boot-time warning:

Enable -Wextra. This found a few real bugs plus a number

also required a few annotations
All things considered it was still worth it so lets try with
this enabled for now.

Subject: [PATCH 0506/1002] kmemleak: Fix scheduling-while-atomic bug
One of the kmemleak changes caused the following
scheduling-while-holding-the-tasklist-lock regression on x86:
BUG: sleeping function called from invalid context at mm/kmemleak.c:795
in_atomic(): 1, irqs_disabled(): 0, pid: 1737, name: kmemleak
2 locks held by kmemleak/1737:

#1: (tasklist_lock){......}, at: [<c10c3bb4>] kmemleak_scan+0x1a9/0x39c
Pid: 1737, comm: kmemleak Not tainted 2.6.31-rc1-tip #59266

[<c100959f>] kernel_thread_helper+0x7/0x10
kmemleak: 834 new suspected memory leaks (see /sys/kernel/debug/kmemleak)
The bit causing it is highly dubious:
static void scan_yield(void)
{
might_sleep();
if (time_is_before_eq_jiffies(next_scan_yield)) {
schedule();
next_scan_yield = jiffies + jiffies_scan_yield;
}
}
It called deep inside the codepath and in a conditional way,
and that is what crapped up when one of the new scan_block()
uses grew a tasklist_lock dependency.
This minimal patch removes that yielding stuff and adds the
proper cond_resched().
The background scanning thread could probably also be reniced
to +10.

Subject: [PATCH 0507/1002] ASoC: Only disable pxa2xx-i2s clocks if we enabled
them
The clock API can't cope with unbalanced enables and disables and
we only enable in hw_params() but try to disable in shutdown.

Subject: [PATCH 0508/1002] drm/i915: enable error detection & state collection
This patch enables error detection by enabling several types of error
interrupts. When an error interrupt is received, the interrupt
handler captures the error state; hopefully resulting in an accurate
set of error data (error type, active head pointer, etc.). The new
record is then available from sysfs. The current code will also dump
the error state to the system log.

Subject: [PATCH 0511/1002] drm/i915: add FIFO watermark support
This patch from jbarnes and myself adds FIFO watermark control to the
driver. This is needed for both power saving features on new platforms
with the so-called "big FIFO" and for controlling FIFO allocation
between pipes in multi-head configurations.
It's also necessary infrastructure to support things like framebuffer
compression and configuration supportability checks (i.e. checking a
configuration against available bandwidth).

+ *
+ * The SR calculation is:

Subject: [PATCH 0512/1002] Fix pci_unmap_addr() et al on i386.
We can run a 32-bit kernel on boxes with an IOMMU, so we need
pci_unmap_addr() etc. to work -- without it, drivers will leak mappings.
To be honest, this whole thing looks like it's more pain than it's
worth; I'm half inclined to remove the no-op #else case altogether.
But this is the minimal fix, which just does the right thing if
CONFIG_DMAR is set.

Subject: [PATCH 0513/1002] Fix iommu address space allocation
This fixes kernel.org bug #13584. The IOVA code attempted to optimise
the insertion of new ranges into the rbtree, with the unfortunate result
that some ranges just didn't get inserted into the tree at all. Then
those ranges would be handed out more than once, and things kind of go
downhill from there.
Introduced after 2.6.25 by ddf02886cbe665d67ca750750196ea5bf524b10b

Subject: [PATCH 0519/1002] intel-iommu: Kill superfluous mapping_lock
Since we're using cmpxchg64() anyway (because that's the only way to do
an atomic 64-bit store on i386), we might as well ditch the extra
locking and just use cmpxchg64() to ensure that we don't add the page
twice.

Subject: [PATCH 0520/1002] drm/i915: enable sdvo lvds scaling function.
Currently we implemented basic sdvo lvds function,
But except for sdvo lvds fixed mode, we can not switch
to other modes, otherwise display get black. The patch
handle three operations to enable sdvo lvds. At first
duplicate sdvo fixed mode for adjustment, then according
to fixed mode line valid all modes, at last adjust input
mode to fit our requirement.

Subject: [PATCH 0523/1002] perf_counter tools: Share rbtree.with the kernel
The tools/perf/util/rbtree.c copy already drifted by three
csets:
4b324126e0c6c3a5080ca3ec0981e8766ed6f1ee
4c60117811171d867d4f27f17ea07d7419d45dae
16c047add3ceaf0ab882e3e094d1ec904d02312d
So remove the copy and use the lib/rbtree.c directly, sharing
the source code while still generating a separate object file,
since tools/perf uses a far more agressive -O6 switch.

- To use rbtrees you'll have to implement your own insert and search cores.
- This will avoid us to use callbacks and to drop drammatically performances.
- I know it's not the cleaner way, but in C (not in C++) to get
- performances and genericity...
-
- Some example of insert and search follows here. The search is a plain
- normal search over an ordered tree. The insert instead must be implemented
- int two steps: as first thing the code must insert the element in
- order as a red leaf in the tree, then the support library function
- rb_insert_color() must be called. Such function will do the
- not trivial work to rebalance the rbtree if necessary.

From: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Wed, 1 Jul 2009 14:46:08 -0300
Subject: [PATCH 0524/1002] perf_counter tools: Share list.h with the kernel
The copy we were using came from another copy I did for the dwarves
(pahole) package, that came from the kernel years ago.
The only function that is used by the perf tools and that isn't in the
kernel is list_del_range, that I'm leaving in the perf tools only for
now.

Subject: [PATCH 0525/1002] perf_counter: Ignore the nmi call frames in the
x86-64 backtraces
About every callchains recorded with perf record are filled up
including the internal perfcounter nmi frame:
perf_callchain
perf_counter_overflow
intel_pmu_handle_irq
perf_counter_nmi_handler
notifier_call_chain
atomic_notifier_call_chain
notify_die
do_nmi
nmi
We want ignore this frame as it's not interesting for
instrumentation. To solve this, we simply ignore every frames
from nmi context.
New example of "perf report -s sym -c" after this patch:
9.59% [k] search_by_key
4.88%
search_by_key
reiserfs_read_locked_inode
reiserfs_iget
reiserfs_lookup
do_lookup
__link_path_walk
path_walk
do_path_lookup
user_path_at
vfs_fstatat
vfs_lstat
sys_newlstat
system_call_fastpath
__lxstat
0x406fb1
3.19%
search_by_key
search_by_entry_key
reiserfs_find_entry
reiserfs_lookup
do_lookup
__link_path_walk

do_path_lookup
user_path_at
vfs_fstatat
vfs_lstat
sys_newlstat
system_call_fastpath
__lxstat
0x406fb1

Subject: [PATCH 0527/1002] PCI: Fix IRQ swizzling for ARI-enabled devices
For many purposes, including interrupt-swizzling, devices with ARI
enabled behave as if they have one device (number 0) and 256 functions.
This probably hasn't bitten us in practice because all ARI devices I've
seen are also IOV devices, and IOV devices are required to use MSI.
This isn't guaranteed, and there are legitimate reasons to use ARI
without IOV, and hence potentially use pin-based interrupts.

Subject: [PATCH 0528/1002] cifs: add new cifs_iget function and convert unix
codepath to use it
cifs: add new cifs_iget function and convert unix codepath to use it
In order to unify some codepaths, introduce a common cifs_fattr struct
for storing inode attributes. The different codepaths (unix, legacy,
normal, etc...) can fill out this struct with inode info. It can then be
passed as an arg to a common set of routines to get and update inodes.
Add a new cifs_iget function that uses iget5_locked to identify inodes.
This will compare inodes based on the uniqueid value in a cifs_fattr
struct.
Rather than filling out an already-created inode, have
cifs_get_inode_info_unix instead fill out cifs_fattr and hand that off
to cifs_iget. cifs_iget can then properly look for hardlinked inodes.
On the readdir side, add a new cifs_readdir_lookup function that spawns
populated dentries. Redefine FILE_UNIX_INFO so that it's basically a
FILE_UNIX_BASIC_INFO that has a few fields wrapped around it. This
allows us to more easily use the same function for filling out the fattr
as the non-readdir codepath.
With this, we should then have proper hardlink detection and can
eventually get rid of some nasty CIFS-specific hacks for handing them.

Subject: [PATCH 0529/1002] drm/i915: fix up a raw 64bit divide
We are seeing compilation failures on i386 in some environments due
to an undefined reference as below:
ERROR: "__udivdi3" [drivers/gpu/drm/i915/i915.ko] undefined!
This is generated due to a raw 64 bit divide in the i915 driver. Fix up
this raw divide.

Subject: [PATCH 0536/1002] perf_counter tools: Enable kernel module symbol
loading in tools
Add the -m/--modules option to perf report and perf annotate,
which enables live module symbol/image loading. To be used
with -k/--vmlinux.
(Also give perf annotate a -P/--full-paths option.)

Subject: [PATCH 0537/1002] tracing: Fix trace_print_seq()
We will lose something if trace_seq->buffer[0] is 0, because the copy length
is calculated by strlen() in seq_puts(), so using seq_write() instead of
seq_puts().
There have a example:
after reboot:
# echo kmemtrace > current_tracer
# echo 0 > options/kmem_minimalistic
# cat trace
# tracer: kmemtrace
#
#
Nothing is exported, because the first byte of trace_seq->buffer[ ]
is KMEMTRACE_USER_ALLOC.
( the value of KMEMTRACE_USER_ALLOC is zero, seeing
kmemtrace_print_alloc_user() in kernel/trace/kmemtrace.c)

Improve the code to be saner and simpler and just print out
the bitfield in a single line using hexa values - not as a
(rather pointless) binary bitfield.
Partially reused Linus's initial fix for this.

Kill this, in favour of just looking to see if the incremented pte
pointer has 'wrapped' onto the next page. Which means we have to check
it _after_ incrementing it, not before.

Check dma_pte_present() and only free the page if there _is_ one.
Kind of surprising that there was no warning about this.

Date: Wed, 1 Jul 2009 23:41:12 +0100
Subject: [PATCH 0549/1002] [ARM] 5579/1: Updated U300 defconfig
This defconfig update selects all the new U300 drivers merged for
2.6.31-rc1 in the merge window and add defaults for the new
config options. It compiles and boots nicely from initramfs on
the U300.

Subject: [PATCH 0550/1002] [ARM] 5581/1: U300 clock updates
This adds a few default locks to the clocks (the clocks were used
before the locks were initialized by code), then renames the clocks
a bit to fit with the latest driver names (some changed during
review). Lastly it moves the initialization of the clock debugfs
entry to module_init() initcall level since the debugfs isn't up
in core_initcall().

Subject: [PATCH 0551/1002] amd-iommu: set evt_buf_size correctly
The setting of this variable got lost during the suspend/resume
implementation. But keeping this variable zero causes a divide-by-zero
error in the interrupt handler. This patch fixes this.

Subject: [PATCH 0554/1002] Btrfs: account for space we may use in fallocate
Using Eric Sandeen's xfstest for fallocate, you can easily trigger a ENOSPC
panic on btrfs. This is because we do not account for data we may use when
doing the fallocate. This patch fixes the problem by properly reserving space,
and then just freeing it when we are done. The reservation stuff was made with
delalloc in mind, so its a little crude for this case, but it keeps the box
from panicing.

Subject: [PATCH 0555/1002] Btrfs: update backrefs while dropping snapshot
The new backref format has restriction on type of backref item. If a tree
block isn't referenced by its owner tree, full backrefs must be used for the
pointers in it. When a tree block loses its owner tree's reference, backrefs
for the pointers in it should be updated to full backrefs. Current
btrfs_drop_snapshot misses the code that updates backrefs, so it's unsafe for
general use.
This patch adds backrefs update code to btrfs_drop_snapshot. It isn't a
problem in the restricted form btrfs_drop_snapshot is used today, but for
general snapshot deletion this update is required.

From 9427216476d4fa75103f39d4b228c47d56ba20da Mon Sep 17 00:00:00 2001
From: Chris Mason <chris.mason@oracle.com>
Date: Thu, 2 Jul 2009 12:26:06 -0400
Subject: [PATCH 0556/1002] Btrfs: honor nodatacow/sum mount options for new
files
The btrfs attr patches unconditionally inherited the inode flags field
without honoring nodatacow and nodatasum. This fix makes sure
we properly record the nodatacow/sum mount options in new inodes.

Subject: [PATCH 0559/1002] perf_counter tools: Create new
chain_for_each_child() iterator
Iterating through children of a node in the callchain tree
shows something that may be quite confusing at a first glance.
The head is the children field of the parent and the list nodes
are in the brothers field of the children.
This is because the childs are linked to the parent as a list
of "brothers" using the "children" list of the parent as a
head:
---------------
| Parent (head) |-------------------------------------
--------------- |
| |
children |
| |
----------- ----------- |
| 1st child |---brother---| 2nd child |---brother-----
----------- -----------
This makes the following strange pattern often occuring:
list_for_each_entry(child, &parent->children, brothers) {
// do something with children
}
Abstract it to chain_for_each_child() to factorize and simplify
this pattern.

Subject: [PATCH 0560/1002] perf_counter tools: Add new OPT_CALLBACK_DEFAULT
option
There is no predefined macro to create an option that can have
a custom value or a default one if none is given.
This patch provides a new helper OPT_CALLBACK_DEFAULT() which
defines such kind of option.
For example, considering an option -c, we want to get the
default value in the following cases:
perf command -c -d
perf command -d -c
And the foo value when it's given:
perf command -c foo -d
perf command -d -c foo
That's also why PARSE_OPT_LASTARG_DEFAULT is extended here to
support default values whatever the position of the option, not
only in the end.
Should it now be renamed to PARSE_OPT_ARG_DEFAULT ?

Subject: [PATCH 0561/1002] perf report: Add support for callchain graph output
Currently, the printing of callchains is done in a single
vertical level, this is the "flat" mode:
8.25% [k] copy_user_generic_string
4.19%
copy_user_generic_string
generic_file_aio_read
do_sync_read
vfs_read
sys_pread64
system_call_fastpath
pread64
This patch introduces a new "graph" mode which provides a
hierarchical output of factorized paths recursively sorted:
8.25% [k] copy_user_generic_string
|
|--4.31%-- generic_file_aio_read
| do_sync_read
| vfs_read
| |
| |--4.19%-- sys_pread64
| | system_call_fastpath
| | pread64
| |
| --0.12%-- sys_read
| system_call_fastpath
| __read
|
|--3.24%-- generic_file_buffered_write
| __generic_file_aio_write_nolock
| generic_file_aio_write
| do_sync_write
| reiserfs_file_write
| vfs_write
| |
| |--3.14%-- sys_pwrite64
| | system_call_fastpath
| | __pwrite64
| |
| --0.10%-- sys_write
[...]
The command line has then changed.
By providing the -c option, the callchain will output in the
flat mode by default.
But you can override it:
perf report -c graph
or
perf report -c flat
You can also pass the abreviated mode:
perf report -c g
or
perf report -c gra
will both make use of the graph mode.

Subject: [PATCH 0562/1002] x86: fix power-of-2 round_up/round_down macros
These macros had two bugs:
- the type of the mask was not correctly expanded to the full size of
the argument being expanded, resulting in possible loss of high bits
when mixing types.
- the alignment argument was evaluated twice, despite the macro looking
like a fancy function (but it really does need to be a macro, since
it works on arbitrary integer types)
Noticed by Peter Anvin, and with a fix that is a modification of his
suggestion (bug noticed by Yinghai Lu).

Increase the command ORB data structure to transport up to 16 bytes long

is notably necessary for READ CAPACITY(16) and friends, i.e. support of
large disks.

Subject: [PATCH 0566/1002] perf_counter tools: Set the minimum percent for
callchains to be displayed
Callchains output may become a burden on a trace because even
rarely hit site are exposed. This can be too much information.
Let the user set a threshold as a minimum percent of hits using
the new pattern for the -c option:
-c mode,min_percent
Example:
$ perf report -s sym -c flat,4
8.25% [k] copy_user_generic_string
4.19%
copy_user_generic_string
generic_file_aio_read
do_sync_read
vfs_read
sys_pread64
system_call_fastpath
pread64
5.39% [k] search_by_key
4.63% 0x00000000009e0a
2.36% [k] memcpy_c
[...]
$ perf report -s sym -c graph,2

Subject: [PATCH 0567/1002] perf_counter tools: Provide helper to print
percents color
Among perf annotate, perf report and perf top, we can find the
common colored printing of percents according to the following
rules:
High overhead = > 5%, colored in red
Mid overhead = > 0.5%, colored in green
Low overhead = < 0.5%, default color
Factorize these multiple checks in a single function named
percent_color_fprintf() and also provide a get_percent_color()
for sites which print percentages and other things at the same
time.

Correct firmware encoding is 8 bit major, 8 bit minor and

driver submission messed it leaving 16 bit major and 8 bit
subversion.
Also fix a infinite loop when cut-thru file firmware is
invalid.

Subject: [PATCH 0572/1002] netxen: avoid frequent firmware reset
Restrict firmware reset to following cases -
o chip rev is NX2031 (firmare doesn't support heartbit).
o firmware is dead.
o previous attempt to init firmware had failed.
o we have got newer file firmware.
This speeds up module load tremendously (by upto 8 sec),
also avoids downtime for NCSI (management) pass-thru
traffic.

Subject: [PATCH 0573/1002] phylib: fixes for PHY_RESUMING state changes
The PHY_HALTED state disables phydev->link, but the link will not be
updated upon entering PHY_RESUMING. Add a call to phy_read_status() to
update the link before entering PHY_RUNNING. If the link is not up at
this point, enter the PHY_NOLINK state instead.
Also, when transitioning from PHY_RESUMING to PHY_RUNNING, calls to
netif_carrier_on() and phydev->adjust_link() are missing. Add the calls
similar to the other transitions to PHY_RUNNING.

Subject: [PATCH 0577/1002] drm/i915: Adjust DisplayPort clocks to use 96MHz
reference
For some reason, the DP clocks were based off a 100MHz reference instead of
the standard 96MHz reference. This caused some DP monitors to fail to lock
to the signal.

Subject: [PATCH 0582/1002] parisc: Remove casts from atomic macros
The atomic operations on parisc are defined as macros. The macros
includes casts which disallows the use of some syntax elements and
produces error like this:
net/phonet/pep.c: In function 'pipe_rcv_status':
net/phonet/pep.c:262: error: lvalue required as left operand of assignment
The patch removes this superfluous casts.

Subject: [PATCH 0584/1002] parisc: fix ldcw inline assembler
There are two reasons to expose the memory *a in the asm:
1) To prevent the compiler from discarding a preceeding write to *a, and
2) to prevent it from caching *a in a register over the asm.
The change has had a few days testing with a SMP build of 2.6.22.19
running on a rp3440.
This patch is about the correctness of the __ldcw() macro itself.
The use of the macro should be confined to small inline functions
to try to limit the effect of clobbering memory on GCC's optimization
of loads and stores.

Subject: [PATCH 0585/1002] parisc: advertise PCI devs after "assign_resources"
Alex Chiang asked me why PARISC was calling pci_bus_add_devices()
and pci_bus_assign_resources() in the opposite order from everyone else.
No reason and I couldn't see any data dependency.
Patch below applies cleanly to 2.6.30-rc2.
Later, I suspected the code worked only because no drivers would be
loaded/ready until much later in the system initialization sequence.
Tested "LBA" code on J6000 (32-bit) and A500 (64-bit SMP) with 2.6.30-rc2.
Not tested with any Dino controllers.
Not tested with PCI-PCI Bridge (TBD).

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons. After more than two years it's
time to remove them finally.
This patch cleans up one of the remaining users. When all such patches
hit mainline we can remove the defines and typedefs finally.
Impact: cleanup
Convert the last remaining users to struct irq_chip and remove the
define.

Subject: [PATCH 0590/1002] parisc: Fix gcc 4.4 warning in lba_pci.c
gcc 4.4 warns about:
drivers/parisc/lba_pci.c: In function 'lba_pat_resources':
drivers/parisc/lba_pci.c:1099: warning: the frame size of 8280 bytes is larger than 4096 bytes
The problem is we declare two large structures on the stack. They don't need
to be on the stack since they are only used during LBA initialization (which
is serialized). Moving to be "static".

Subject: [PATCH 0592/1002] parisc: fix "delay!" timer handling
Rewrote timer_interrupt() to properly handle the "delayed!" case.
If we used floating point math to compute the number of ticks that had
elapsed since the last timer interrupt, it could take up to 12K cycles
(emperical!) to handle the interrupt. Existing code assumed it would
never take more than 8k cycles. We end up programming Interval Timer
to a value less than "current" cycle counter. Thus have to wait until
Interval Timer "wrapped" and would then get the "delayed!" printk that
I moved below.
Since we don't really know what the upper limit is, I prefer to read
CR16 again after we've programmed it to make sure we won't have to
wait for CR16 to wrap.
Further, the printk was between reading CR16 (cycle couner) and writing CR16
(the interval timer). This would cause us to continue to set the interval
timer to a value that was "behind" the cycle counter. Rinse and repeat.
So no printk's between reading CR16 and setting next interval timer.
Tested on A500 (550 Mhz PA8600).

Kyle, Helge, and other parisc's,
Please test on 32-bit before committing.
I think I have it right but recognize I might not.
TODO: I wanted to use "do_div()" in order to get both remainder
and value back with one division op. That should help with the
latency alot but can be applied seperately from this patch.
thanks,
grant

Subject: [PATCH 0593/1002] parisc: ensure broadcast tlb purge runs single
threaded
The TLB flushing functions on hppa, which causes PxTLB broadcasts on the system
bus, needs to be protected by irq-safe spinlocks to avoid irq handlers to deadlock
the kernel. The deadlocks only happened during I/O intensive loads and triggered
pretty seldom, which is why this bug went so long unnoticed.

Rename ->prelinked to ->adjust_symbols and making what was done
only for prelinked libraries also to ET_EXEC binaries, such as
/usr/bin/git:
[acme@doppio pahole]$ readelf -h /usr/bin/git | grep Type
Type: EXEC (Executable file)
[acme@doppio pahole]$
And after installing the 'git-debuginfo' package, I get correct results:

And I guess this will fix the problems Mike were seeing too:

Subject: [PATCH 0607/1002] sh-sci: update receive error handling for muxed
irqs
This patch updates the receive error code for muxed
interrupts in the sh-sci driver.
Receive error interrupts may be generated by the hardware
if RE or REIE bits in SCSCR are set. Update the muxed
interrupt handling code to acknowledge error interrupts
if RE or REIE is set, instead of only acknowledging if
REIE is set.
Without this patch error interrupts may be generated but
never acked resulting in a "nobody cared" crash.

When doing register reads, it is possible for there to be a stale
data ready bit set which will cause subsequent reads to return
prematurely with incorrect data. This patch fixes the issues by
ensuring stale data is cleared before starting another transaction.

Locked instructions on two cache lines at once are painful. If
atomic64_t uses two cache lines, my test program is 10x slower.
The chance for that is significant: 4/32 or 12.5%.
Make sure an atomic64_t is 8 bytes aligned.

Subject: [PATCH 0615/1002] x86: atomic64: Move the 32-bit atomic64_t
implementation to a .c file
Linus noted that the atomic64_t primitives are all inlines
currently which is crazy because these functions have a large
register footprint anyway.
Move them to a separate file: arch/x86/lib/atomic64_32.c
Also, while at it, rename all uses of 'unsigned long long' to
the much shorter u64.
This makes the appearance of the prototypes a lot nicer - and
it also uncovered a few bugs where (yet unused) API variants
had 'long' as their return type instead of u64.
[ More intrusive changes are not yet done in this patch. ]

Subject: [PATCH 0616/1002] x86: atomic64: Improve atomic64_read()
Linus noticed that the 32-bit version of atomic64_read() was
being overly complex with re-reading the value and doing a
retry loop over that.
Instead we can just rely on cmpxchg8b returning either the new
value or returning the current value.
We can use any 'old' value, which will be faster as it can be
loaded via immediates. Using some value that is not equal to
the real value in memory the instruction gets faster.
This also has the advantage that the CPU could avoid dirtying
the cacheline.

Subject: [PATCH 0618/1002] x86: atomic64: Improve atomic64_add_return()
Linus noted (based on Eric Dumazet's numbers) that we would
probably be better off not trying an atomic_read() in
atomic64_add_return() but intead intentionally let the first
cmpxchg8b fail - to get a cache-friendly 'give me ownership
of this cacheline' transaction. That can then be followed
by the real cmpxchg8b which sets the value local to the CPU.

Subject: [PATCH 0619/1002] x86: atomic64: Reduce size of functions
cmpxchg8b is a huge instruction in terms of register footprint,
we almost never want to inline it, not even within the same
code module.
GCC 4.3 still messes up for two functions, under-judging the
true cost of this instruction - so annotate two key functions
to reduce the bloat:

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Linus noticed that atomic64_xchg() uses atomic_read(), which
happens to work because atomic_read() is a macro so the
.counter value gets u64-read on 32-bit too - but this is really
bogus and serious bugs are waiting to happen.
Change atomic_read() to be a type-safe inline, and this exposes
the atomic64 bogosity as well:

Masami reported:
> Since the fixmap pages are assigned higher address to lower,
> text_poke() has to use it with inverted order (FIX_TEXT_POKE1
> to FIX_TEXT_POKE0).
I prefer to just invert the order of the fixmap declaration.
It's simpler and more straightforward.
Backward fixmaps seems to be used by both x86 32 and 64.
It's really rare but a nasty bug, because it only hurts when
instructions to patch are crossing a page boundary. If this
happens, the fixmap write accesses will spill on the following
fixmap, which may very well crash the system. And this does not
crash the system, it could leave illegal instructions in place.
Thanks Masami for finding this.
It seems to have crept into the 2.6.30-rc series, so this calls
for a -stable inclusion.

Subject: [PATCH 0624/1002] x86, kvm: Fix section mismatches in kvm.c
The function paravirt_ops_setup() has been refering the
variable no_timer_check, which is a __initdata. Thus generates
the following warning. paravirt_ops_setup() function is called
from kvm_guest_init() which is a __init function. So to fix
this we mark paravirt_ops_setup as __init.
The sections-check output that warned us about this was:
LD arch/x86/built-in.o
WARNING: arch/x86/built-in.o(.text+0x166ce): Section mismatch in
reference from the function paravirt_ops_setup() to the variable
.init.data:no_timer_check
The function paravirt_ops_setup() references
the variable __initdata no_timer_check.
This is often because paravirt_ops_setup lacks a __initdata
annotation or the annotation of no_timer_check is wrong.

Subject: [PATCH 0627/1002] x86: atomic64: Code atomic(64)_read and
atomic(64)_set in C not CPP
Occasionally we get bugs where atomic_read or atomic_set are
used on atomic64_t variables or vice versa. These bugs don't
generate warnings on x86 because atomic_read and atomic_set are
coded as macros rather than C functions, so we don't get any
type-checking on their arguments; similarly for atomic64_read
and atomic64_set in 64-bit kernels.
This converts them to C functions so that the arguments are
type-checked and bugs like this will get caught more easily. It
also converts atomic_cmpxchg and atomic_xchg, and
atomic64_cmpxchg and atomic64_xchg on 64-bit, so we get
type-checking on their arguments too.
Compiling a typical 64-bit x86 config, this generates no new
warnings, and the vmlinux text is 86 bytes smaller.

Subject: [PATCH 0629/1002] ALSA: hda - Add GPIO1 control at muting with HP
laptops
HP laptops with AD1984A codecs (at least mobile models) need to set
GPIO1 appropriately to indicate the mute state. The BIOS checks this
bit to judge whether the mute on or off is sent via F8 key.
Without changing this bit, the BIOS can be confused and may toggle
the mute wrongly.

Subject: [PATCH 0630/1002] ALSA: hda - Improve ASUS eeePC 1000 mixer
The mixer elements created for ASUS eeePC 1000 with ALC269 aren't
standard but strange words like "LineOut". Rename the element names
to follow the standard one like "Headphone" and "Speaker".
Also, split the volumes to each so that the virtual master can control
them.
The alc269_fujitsu_mixer is removed because it's now identical with
the new eeepc mixer.

Subject: [PATCH 0632/1002] NFSD: Don't hold unrefcounted creds over call to
nfsd_setuser()
nfsd_open() gets an unrefcounted pointer to the current process's effective
credentials at the top of the function, then calls nfsd_setuser() via
fh_verify() - which may replace and destroy the current process's effective
credentials - and then passes the unrefcounted pointer to dentry_open() - but
the credentials may have been destroyed by this point.
Instead, the value from current_cred() should be passed directly to
dentry_open() as one of its arguments, rather than being cached in a variable.
Possibly fh_verify() should return the creds to use.
This is a regression introduced by
745ca2475a6ac596e3d8d37c2759c0fbe2586227 "CRED: Pass credentials through
dentry_open()".

Subject: [PATCH 0638/1002] MIPS: Define __arch_swab64 for all mips r2 cpus
Some CPUs implement mipsr2, but because they are a super-set of mips64r2 do
not define CONFIG_CPU_MIPS64_R2. Cavium OCTEON falls into this category.
We would still like to use the optimized implementation, so since we have
already checked for CONFIG_CPU_MIPSR2, checking for CONFIG_64BIT instead of
CONFIG_CPU_MIPS64_R2 is sufficient.

Subject: [PATCH 0639/1002] MIPS: CMP: Extend the GIC IPI interrupts beyond 32
This patch extends the GIC interrupt handling beyond the current 32 bit
range as well as extending the number of interrupts based on the number
of CPUs.

Subject: [PATCH 0644/1002] MIPS: BC47xx: Fix SSB irq setup
The current ssb irq setup in ssb_mipscore_init has the problem that it
configures some device on some irq without checking that the irq is not
taken by an other device.
For example in my case PCI host is on irq 0 and IPSEC on irq 3.
The current code:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host
But now IPSEC irq is not routed anymore to the mips code and dev->irq is
wrong. This causes a problem described in [1].
This patch tries to solve the problem by making set_irq configure the
device we want to take the irq on the shared irq0. The previous example
becomes:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host:
- irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
I also added some code to print the irq configuration after irq setup to
allow easier debugging. And I add extra checking in ssb_mips_irq to report
device without irq or device with not routed irq.

Subject: [PATCH 0645/1002] MIPS: 64-bit: Fix o32 core dump
If an o32 process generates a core dump on a 64 bit kernel, the core file
will not be correctly recognized. This is because ELF_CORE_COPY_REGS and
ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use
the default register set which would be CONFIG_64BIT in asm/elf.h.
So we'll switch to use the right register defines in this situation by
checking for WANT_COMPAT_REG_H and use the right defines of
ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.
[Ralf: made ELF_CORE_COPY_TASK_REGS() bullet-proof against funny arguments.]

From: Ralf Baechle <ralf@linux-mips.org>
Date: Fri, 3 Jul 2009 07:11:15 +0100
Subject: [PATCH 0649/1002] MIPS: Fix CONFIG_FLATMEM version of pfn_valid()
For systems which do not define PHYS_OFFSET as 0 pfn_valid() may falsely
have returned 0 on most configurations. Bug introduced by commit
752fbeb2e3555c0d236e992f1195fd7ce30e728d (linux-mips.org) rsp.
6f284a2ce7b8bc49cb8455b1763357897a899abb (kernel.org) titled "[MIPS]
FLATMEM: introduce PHYS_OFFSET."

Subject: [PATCH 0650/1002] x86: atomic64: Export APIs to modules
atomic64_t primitives are used by a handful of drivers,
so export the APIs consistently. These were inlined
before.
Also mark atomic64_32.o a core object, so that the symbols
are available even if not linked to core kernel pieces.

Subject: [PATCH 0651/1002] x86: atomic64: Improve atomic64_xchg()
Remove the read-first logic from atomic64_xchg() and simplify
the loop.
This function was the last user of __atomic64_read() - remove it.
Also, change the 'real_val' assumption from the somewhat quirky
1ULL << 32 value to the (just as arbitrary, but simpler) value
of 0.

Subject: [PATCH 0652/1002] cciss: Ignore stale commands after reboot
When doing an unexpected shutdown like kexec the cciss
firmware might still have some commands in flight, which
it is trying to complete.
The driver is doing it's best on resetting the HBA,
but sadly there's a firmware issue causing the firmware
_not_ to abort or drop old commands.
So the firmware will send us commands which we haven't
accounted for, causing the driver to panic.
With this patch we're just ignoring these commands as
there is nothing we could be doing with them anyway.

Subject: [PATCH 0653/1002] block: don't merge requests of different failfast
settings
Block layer used to merge requests and bios with different failfast
settings. This caused regular IOs to fail prematurely when they were
merged into failfast requests for readahead.
Niel Lambrechts could trigger the problem semi-reliably on ext4 when
resuming from STR. ext4 uses readahead when reading inodes and
combined with the deterministic extra SATA PHY exception cycle during
resume on the specific configuration, non-readahead inode read would
fail causing ext4 errors. Please read the following thread for
details.
http://lkml.org/lkml/2009/5/23/21
This patch makes block layer reject merging if the failfast settings
don't match. This is correct but likely to lower IO performance by
preventing regular IOs from mingling into surrounding readahead
requests. Changes to allow such mixed merges and handle errors
correctly will be added later.

Subject: [PATCH 0661/1002] IPv6: preferred lifetime of address not getting
updated
There's a bug in addrconf_prefix_rcv() where it won't update the
preferred lifetime of an IPv6 address if the current valid lifetime
of the address is less than 2 hours (the minimum value in the RA).
For example, If I send a router advertisement with a prefix that
has valid lifetime = preferred lifetime = 2 hours we'll build
this address:
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
valid_lft 7175sec preferred_lft 7175sec
If I then send the same prefix with valid lifetime = preferred
lifetime = 0 it will be ignored since the minimum valid lifetime
is 2 hours:
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
valid_lft 7161sec preferred_lft 7161sec
But according to RFC 4862 we should always reset the preferred lifetime
even if the valid lifetime is invalid, which would cause the address
to immediately get deprecated. So with this patch we'd see this:
5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:21f:29ff:fe5a:ef04/64 scope global deprecated dynamic
valid_lft 7163sec preferred_lft 0sec
The comment winds-up being 5x the size of the code to fix the problem.
Update the preferred lifetime of IPv6 addresses derived from a prefix
info option in a router advertisement even if the valid lifetime in
the option is invalid, as specified in RFC 4862 Section 5.5.3e. Fixes
an issue where an address will not immediately become deprecated.

register.
The hardware semaphore covers the configuration register as well as the
ICB registers. The ICB high and low regs contain the address of the
initialization control block and the config register is used to signal
the hardware that a block is ready to be downloaded. Currently we were
only protecting the ICB regs. This changes expands to cover the config
register as well.

Subject: [PATCH 0667/1002] qlge: Fix MAC address bonding issue.
This addes functionality to set/clear the MAC address in the hardware
when the link goes up/down.
The MAC address register is persistent across function resets. In
bonding the same address can bounce from one port to the other. This
can cause packets to be delivered to the wrong port.
This patch clears the MAC address in the hardware when the link is down
and sets it when the link comes up.
It was found that pulling/pushing the cable from one port to another
causes the same MAC address to be in both ports.
The next patch in this series will use this functionality as well.

Subject: [PATCH 0668/1002] qlge: Add/use function for link up/down.
We need to set/clear the mac address register when the link goes up/down
respectively. Without this both ports of a 2-port device can end up
with the same mac address in a bonding scenario.
The new ql_link_on() and ql_link_off() will also be used in handling
certain firmware events.

Subject: [PATCH 0670/1002] ixgbe: fix issues with failing to detect insert of
unsupported module
Several small fixes around negative test case of the insertion of a
IXGBE_ERR_NOT_SUPPORTED module.
- mdio45_probe call was always failing due to mdio.prtad not being
set. The function set to mdio.mdio_read was still working as we just
happen to always be at prtad == 0. This will allow us to set the phy_id
and phy.type correctly now.
- There was timing issue with i2c calls when initiated from a tasklet.
A small delay was added to allow the electrical oscillation to calm down.
- Logic change in ixgbe_sfp_task that allows NOT_SUPPORTED condition
to be recognized.

Subject: [PATCH 0671/1002] ixgbe: fix regression on some 82598 adapters
The change to check the SFP+ module again on open() was
causing the XFP (non-SFP+) adapters to be rejected. We
only want to try and re-identify the SFP+ module if the
original probe found that this device was an SFP+ device.
So for this code path (driver loaded with SFP module, module
inserted, ifconfig up of the device) the type will be
ixgbe_phy_unknown for an unidentified SFP+ module. So we
only check if that is the case.
This problem also shows up on Copper devices.

Subject: [PATCH 0672/1002] ixgbe: fix inconsistent SFP/SFP+ failure results.
Currently if we loaded the driver, insert an unsupported module, and then
attempt to "ifconfig up" the device it will be brought down but the netdev
would not be unregistered. This behavior is different than all other
code paths. This patch corrects that by down'ing the device and then
scheduling the sfp_config_module_task tasklet. The tasklet will detect
this condition (like it does with other code paths) and do the
unregister_netdev().
I also removed the log message as this condition (an unsupported SFP+
module) will be logged in sfp_config_module_task.

Subject: [PATCH 0675/1002] e1000e: delay after LCD reset and proper checks for
PHY configuration done
A previous workaround for 82578 to avoid link stall causes some PHY
registers to get cleared inadvertently. Add a delay after all LCD resets
to make sure PHY registers are in a stable state before continuing. Also,
after resets check the EEC register for the state of PHY configuration
performed by the MAC for ICH9 and earlier parts (as done before), but check
the LAN_INIT_DONE bit in the STATUS register for ICH10 and newer parts (EEC
doesn't exist in these newer parts).

mode
Occasionally we may see an interrupt without an event in the eq.
In intx, we currently see the event queue and return IRQ_NONE causing
a the irq to be disabled ("no one cared".) Instead, read the CEV_ISR
reg to check the existence of the interrupt.

Subject: [PATCH 0684/1002] intel-iommu: Fix reattaching of devices to identity
mapping domain
When we reattach a device to the si_domain (because it's been removed
from a VM), we weren't calling domain_context_mapping() to actually tell
the hardware about that.
We should really put the call to domain_context_mapping() into
domain_add_dev_info() -- we never call the latter without also doing the
former, and we can keep the error paths simple that way. But that's a
cleanup which can wait for 2.6.32 now.

Subject: [PATCH 0691/1002] video: sm501fb: Early initialization of mm_lock
mutex.
Commit 537a1bf059fa312355696fa6db80726e655e7f17 (fbdev: add mutex for
fb_mmap locking) introduces a ->mm_lock mutex for protecting smem
assignments. Unfortunately in the case of sm501fb these happen quite
early in the initialization code, well before the mutex_init() that takes
place in register_framebuffer(), leading to:
Badness at kernel/mutex.c:207
Pid : 1, Comm: swapper
CPU : 0 Not tainted (2.6.31-rc1-00284-g529ba0d-dirty #2273)
PC is at __mutex_lock_slowpath+0x72/0x1bc
PR is at __mutex_lock_slowpath+0x66/0x1bc
...
matroxfb appears to have the same issue and has solved it with an early
mutex_init(), so we do the same for sm501fb.

Subject: [PATCH 0694/1002] intel-iommu: Don't use identity mapping for PCI
devices behind bridges
Our current strategy for pass-through mode is to put all devices into
the 1:1 domain at startup (which is before we know what their dma_mask
will be), and only _later_ take them out of that domain, if it turns out
that they really can't address all of memory.
However, when there are a bunch of PCI devices behind a bridge, they all
end up with the same source-id on their DMA transactions, and hence in
the same IOMMU domain. This means that we _can't_ easily move them from
the 1:1 domain into their own domain at runtime, because there might be DMA
in-flight from their siblings.
So we have to adjust our pass-through strategy: For PCI devices not on
the root bus, and for the bridges which will take responsibility for
their transactions, we have to start up _out_ of the 1:1 domain, just in
case.
This fixes the BUG() we see when we have 32-bit-capable devices behind a
PCI-PCI bridge, and use the software identity mapping.
It does mean that we might end up using 'normal' mapping mode for some
devices which could actually live with the faster 1:1 mapping -- but
this is only for PCI devices behind bridges, which presumably aren't the
devices for which people are most concerned about performance.

Subject: [PATCH 0696/1002] nilfs2: remove unlikely directive causing
mis-conversion of error code
The following error code handling in nilfs_segctor_write() function
wrongly converted negative error codes to a truth value (i.e. 1):
err = unlikely(err) ? : res;
which originaly meant to be
err = err ? : res;
This mis-conversion caused that write or sync functions receive the
unexpected error code. This fixes the bug by removing the unlikely
directive.

Subject: [PATCH 0697/1002] nilfs2: fix hang problem of log writer which occurs
after write failures
Leandro Lucarella gave me a report that nilfs gets stuck after its
write function fails.
The problem turned out to be caused by bugs which leave writeback flag
on pages. This fixes the problem by ensuring to clear the writeback
flag in error path.

Subject: [PATCH 0702/1002] perf report: Use a modifiable string for default
callchain options
If the user doesn't provide options to tune his callchain output
(ie: if he uses -c without arguments) then the default value passed
in the OPT_CALLBACK_DEFAULT() macro is used.
But it's parsed later by strtok() which will replace comma separators
to a zero. This may segfault as we are using a read-only string.
Use a modifiable one instead, and also fix the "100%" default
minimum threshold value by turning it into a 0 (output every callchains)
as it was intended in the origin.

The default callchain parameters are set to use the flat mode and never

But flat mode is boring compared to graph mode.
Also the number of callchains may be very high if none is
filtered.
Let's change this to set the graph view and a minimum overhead of 0.5%
as default parameters.

Subject: [PATCH 0704/1002] perf_counter tools: callchains: Manage the cumul
hits on the fly
The cumul hits are the number of hits of every childs of a node
plus the hits of the current nodes, required for percentage
computing of a branch.
Theses numbers are calculated during the sorting of the branches of
the callchain tree using a depth first postfix traversal, so that
cumulative hits are propagated in the right order.
But if we plan to implement percentages relative to the parent and not
absolute percentages (relative to the whole overhead), we need to know
the cumulative hits of the parent before computing the children
because the relative minimum acceptable number of entries (ie: minimum
rate against the cumulative hits from the parent) is the basis to
filter the children against a given rate.
Then we need to handle the cumul hits on the fly to prepare the
implementation of relative overhead rates.

Subject: [PATCH 0705/1002] perf report: Add "Fractal" mode output - support
callchains with relative overhead rate
The current callchain displays the overhead rates as absolute:
relative to the total overhead.
This patch provides relative overhead percentage, in which each
branch of the callchain tree is a independant instrumentated object.
This provides a 'fractal' view of the call-chain profile: each
sub-graph looks like a profile in itself - relative to its parent.
You can produce such output by using the "fractal" mode
that you can abbreviate via f, fr, fra, frac, etc...
./perf report -s sym -c fractal

Subject: [PATCH 0707/1002] V4L/DVB (12134): vivi: bug: don't assume that S_STD
will be called before streaming
precalculate_bars() improved vivi performance. However, it assumed that
always before streaming, the driver would call VIDIOC_S_STD. This is not
an API requirement, and the testing apps don't do that.
Due to that, a regression were caused by the patch that added it.
This patch moves the precalculate_bars to the proper place of the code,
calling it at buffer_prepare() callback.

Subject: [PATCH 0709/1002] powerpc/4xx: Have Warp take advantage of GPIO LEDs
default-state = keep
The GPIO LEDS driver now has a default state of "keep". Update the Warp DTS
and platform file to take advantage of this new state. This removes the
hardcoding of the two LEDs on the Warp.

Subject: [PATCH 0710/1002] powerpc/44x: Fix build error with -Werror for Warp
platform
With -Werror enabled during the build, the warp.c file fails to build
due to the temp_isr function not containing a return statement. This
fixes the build error and documents that the function never returns.

Subject: [PATCH 0712/1002] [ARM] pgtable: swp pte layout documentation,
definitions, and check
Document the layout of our swp PTE entries, adding definitions for
the bit masks/shifts/sizes, and implement MAX_SWAPFILES_CHECK()
such that we fail to build if we are unable to properly encode the
swp type field.

Subject: [PATCH 0716/1002] UBIFS: slightly optimize write-buffer timer usage
This patch adds the following minor optimization:
1. If write-buffer does not use the timer, indicate it with the
wbuf->no_timer variable, instead of using the wbuf->softlimit
variable. This is better because wbuf->softlimit is of ktime_t
type, and the ktime_to_ns function contains 64-bit multiplication.
2. Do not call the 'hrtimer_cancel()' function for write-buffers
which do not use timers.
3. Do not cancel the timer in 'ubifs_put_super()' because the
synchronization function does this.
This patch also removes a confusing comment.

UBIFS uses a bdi device per volume, but does not care to hand out unique
names to each of them. This causes an error when trying to mount more
than one volumes. Append the UBI volume and device ID to avoid that.

Subject: [PATCH 0725/1002] UBI: remove bogus debugging checks
The 'paranoid_check_empty()' is bogus because, which is easilly
seen on NOR flash, which has long erase cycles, and which may
easilly end-up with half-erased eraseblocks. In this case the
paranoid check fails. I is just wrong to assume that PEBs which
do not have EC headers always contain all 0xFF. Such assumption
should not be made on the I/O level, which is quite low.
Thus, just kill the check.

Subject: [PATCH 0726/1002] UBI: add image sequence number to EC header
An image sequence number is added to the UBI erase-counter header
to be able determine if the root file system contains a mixture
of old and new images (because the flashing failed to complete).
A change to nolo is also needed for this to take effect.

Subject: [PATCH 0727/1002] UBI: nicify image sequence number handling
Move the image seq. number handling from I/O level to the scanning
lever, where it really belongs to. Move the @image_seq_set variable
to the @struct ubi_scan_info structure, which exists only during
scanning.

Subject: [PATCH 0733/1002] V4L/DVB (12181): get_dvb_firmware: Add Yuan MPC718
MT352 DVB-T "firmware" extraction
Add routine to support extracting the MT352 DVB-T demodulator initialization
sequence for Yuan MPC718 cards for use by the cx18 driver.
This routine uses a hueristic for extracting a good sequence. It should work
on all different versions of the "yuanrap.sys" file, given the way the MT352
tuning sequences are stored in all versions of that file I have seen so far.
However, the current patch simply looks for one specific archive URL.

Subject: [PATCH 0734/1002] V4L/DVB (12182): cx18: Add DVB-T support for Yuan
MPC-718 cards with an MT352 or ZL10353
Add DVB-T support for Yuan MPC-718 cards with an MT352 or ZL10353 demodulator.
There are apparently some units with a DiBcom demodulator which could be
supported by one of the dib7000 modules - but this is not implemented in the
cx18 driver (yet).
Due to lack of porgramming details for the MT352 and the mt352 module requiring
a "demod_init" function, a "firmware" must be obtained and loaded to get
DVB-T working for Yuan MPC-718 cards with an MT352.

Subject: [PATCH 0741/1002] V4L/DVB (12173): mt9v011: properly calculate image
resolution registers
Instead of working with a table of precalculated values, fill them with
the proper values. Also, adds format functions that allow changing the
resolution, by cropping the image to the center of the sensor.
While here, move the sensor version check to the probe routine, to
indicate to the caller if the sensor is not supported by this driver.
Also, fixes a stupid bug where we're using &buffer[] instead of
buffer[].

Subject: [PATCH 0742/1002] V4L/DVB (12174): mt9v011: let's stick with
datasheet values where it works
The original driver for Silvercrest cameras were using some values that
are different from what datasheet says. As result, it was taken very
less snapshots per second than expected.
A test with the datasheet values showed that they work fine and give a
better frame rate. So, let's stick with datasheet values.

Subject: [PATCH 0743/1002] V4L/DVB (12138): em28xx: add support for
Silvercrest Webcam
This webcam uses a em2710 chipset, that identifies itself as em2820,
plus a mt9v011 sensor, and a DY-301P lens.
It needs a few different initializations than a normal em28xx device.
Thanks to Hans de Goede <hdegoede@redhat.com> and Douglas Landgraf
<dougsland@redhat.com> for providing the acces for the webcam during
this weekend, I could make a patch for it while returning back from
FISL/Fudcom LATAM 2009.

Subject: [PATCH 0745/1002] V4L/DVB (12156): em28xx: Fix tuning for Terratec
Cinergy T XS USB (zl10353 version)
Fix the code so that the zl10353 version of the Terratec Cinergy T XS USB
starts working again. This includes fixing what must have been a typo in the
GPIO definition for the digital side of the board, and setting of the
disable_i2c_gate_ctrl property for the zl10353 config, so that the i2c bus
doesn't get wedged the first time something tries to close the gate.
Also, add a printk() making clear that the mt352 version still isn't
supported. This issue is still being actively debugged, but in the meantime
at least the dmesg output will show a very clear error...
Thanks to Jelle de Jong for providing sample hardware to test with.
Thanks to Simon Kenyon for testing various patches and providing SSH access to
his environment so I could debug with access to a valid signal source.

Discovered the bug that were limiting the output format to just RGB565.
Now, it is possible to output image at Bayer format (the original one,
as generated by Silvercrest sensor, and two others), and also on YUY.
Adds Bayer formats also to the driver.

in MPC718 firmware extraction logic
The extraction routine for the MPC718 "firmware" had 2 bugs in it, where one
bug masked the effect of the other. The loop iteration should have set
$prevlen = $currlen at the end of the loop, and the if() check should have used
&& instead of || for deciding if the firmware length is reasonable.

Subject: [PATCH 0753/1002] tun: Fix device unregister race
It is currently possible for an asynchronous device unregister
to cause the same tun device to be unregistered twice. This
is because the unregister in tun_chr_close only checks whether
__tun_get(tfile) != NULL. This however has nothing to do with
whether the device has already been unregistered. All it tells
you is whether __tun_detach has been called.
This patch fixes this by using the most obvious thing to test
whether the device has been unregistered.
It also moves __tun_detach outside of rtnl_unlock since nothing
that it does requires that lock.

The FW supports coalescing in 12us granularity, and so value of less then 12

Subject: [PATCH 0757/1002] drivers/net/smsc911x.c: Fix resource size off by 1
error
The call resource_size(res) returns res->end - res->start + 1 and thus the
second change is semantics-preserving. res_size is then used as the second
argument of a call to request_mem_region, and the memory allocated by this
call appears to be the same as what is released in the two calls to
release_mem_region. So the size argument for those calls should be
resource_size(size) as well. Alternatively, in the second call to
release_mem_region, the second argument could be res_size, as that variable
has already been initialized at the point of this call.
The problem was found using the following semantic patch:

We might have a race in napi_schedule(), leaving interrupts disabled forever.

Subject: [PATCH 0759/1002] dsa: fix 88e6xxx statistics counter snapshotting
The bit that tells us whether a statistics counter snapshot operation
has completed is located in the GLOBAL register block, not in the
GLOBAL2 register block, so fix up mv88e6xxx_stats_wait() to poll the
right register address.

Subject: [PATCH 0760/1002] microblaze: fall back on generic header files for
the ABI
Almost all of the ABI relevant header files now have generic
versions, so use those now in order to reduce the amount
of architecture specific code.

From 14f8738976991d2f8fb6ab6e10e9003562c3d6bb Mon Sep 17 00:00:00 2001
From: Remis Lima Baima <remis.developer@googlemail.com>
Date: Thu, 18 Jun 2009 19:55:32 +0200
Subject: [PATCH 0761/1002] microblaze: use the generic lib/checksum.c
The microblaze checksum code is mostly identical to
the asm-generic+lib version, so use that instead.

From 0a58458341fd571e521be542ff746a4a8995980c Mon Sep 17 00:00:00 2001
From: Remis Lima Baima <remis.developer@googlemail.com>
Date: Thu, 18 Jun 2009 19:55:33 +0200
Subject: [PATCH 0762/1002] microblaze: convert all simple headers to use
asm-generic
All the simple microblaze header files were adapted to use their
asm-generic implementations. These files are more simple and were quite
straightforward to change.
fb.h, vga.h and parport.h previously did not exist, using
the generic version makes it possible to build more drivers
successfully in allyesonfig.

From 3183e06863f49a500fc76427db4d60825a26f81b Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>
Date: Thu, 18 Jun 2009 19:55:29 +0200
Subject: [PATCH 0763/1002] microblaze: clean up signal handling
When legacy signal handling is disabled, the
arch/microblaze/kernel/signal.c implementation can
be much simpler, as most of it is handled generically
from kernel/signal.c.
This is also a prerequisite for using the generic
asm/unistd.h, which does not provide __NR_sigreturn,
because this macro is referenced by the current signal.c
implementation.

Subject: [PATCH 0764/1002] microblaze: use generic syscalls.h
The prototypes in syscalls.h all make sense for
microblaze, but for some of them, the actual implementation
in sys_microblaze.c needs to be adapted.

Subject: [PATCH 0769/1002] sctp: fix warning at inet_sock_destruct() while
release sctp socket
Commit 'net: Move rx skb_orphan call to where needed' broken sctp protocol
with warning at inet_sock_destruct(). Actually, sctp can do this right with
sctp_sock_rfree_frag() and sctp_skb_set_owner_r_frag() pair.
sctp_sock_rfree_frag(skb);
sctp_skb_set_owner_r_frag(skb, newsk);
This patch not revert the commit d55d87fdff8252d0e2f7c28c2d443aee17e9d70f,
instead remove the sctp_sock_rfree_frag() function.

Subject: [PATCH 0776/1002] sys_sync(): fix 16% performance regression in ffsb
create_4k test
I run many ffsb test cases on JBODs (typically 13/12 disks). Comparing
with kernel 2.6.30, 2.6.31-rc1 has about 16% regression with
ffsb_create_4k. The sub test case creates files continuously for 10
minitues and every file is 1MB.
Bisect located below patch.
5cee5815d1564bbbd505fea86f4550f1efdb5cd0 is first bad commit

Author: Jan Kara <jack@suse.cz>

vfs: Make sys_sync() use fsync_super() (version 4)
It is unnecessarily fragile to have two places (fsync_super() and do_sync())
doing data integrity sync of the filesystem. Alter __fsync_super() to
accommodate needs of both callers and use it. So after this patch
__fsync_super() is the only place where we gather all the calls needed to
properly send all data on a filesystem to disk.
As a matter of fact, ffsb calls sys_sync in the end to make sure all data
is flushed to disks and the flushing is counted into the result. vmstat
shows ffsb is blocked when syncing for a long time. With 2.6.30, ffsb is
blocked for a short time.
I checked the patch and did experiments to recover the original methods.
Eventually, the root cause is the patch deletes the calling to
wakeup_pdflush when syncing, so only ffsb is blocked on disk I/O.
wakeup_pdflush could ask pdflush to write back pages with ffsb at the
same time.

Subject: [PATCH 0777/1002] elf: fix multithreaded program core dumping on arm
Fix the multithread program core thread message error.
This issue affects arches with neither has CORE_DUMP_USE_REGSET nor
ELF_CORE_COPY_TASK_REGS, ARM is one of them.
The thread message of core file is generated in elf_dump_thread_status.
The register values is set by elf_core_copy_task_regs in this function.
If an arch doesn't define ELF_CORE_COPY_TASK_REGS,
elf_core_copy_task_regs() will do nothing. Then the core file will not
have the register message of thread.
So add elf_core_copy_regs to set regiser values if ELF_CORE_COPY_TASK_REGS
doesn't define.
The following is how to reproduce this issue:
cat 1.c
#include <stdio.h>
#include <pthread.h>
#include <assert.h>
void td1(void * i)
{
while (1)
{
printf ("1\n");
sleep (1);
}
return;
}
void td2(void * i)
{
while (1)
{
printf ("2\n");
sleep (1);
}
return;
}
int
main(int argc,char *argv[],char *envp[])
{
pthread_t t1,t2;
pthread_create(&t1, NULL, (void*)td1, NULL);
pthread_create(&t2, NULL, (void*)td2, NULL);
sleep (10);
assert(0);
return (0);
}
arm-xxx-gcc -g -lpthread 1.c -o 1
copy 1.c and 1 to a arm board.
Goto this board.
ulimit -c 1800000
./1
# ./1
1
2
1
...
...
1
1: 1.c:37: main: Assertion `0' failed.
Aborted (core dumped)
Then you can get a core file.
gdb 1 core.xxx
Without the patch:
(gdb) info threads
3 process 909 0x00000000 in ?? ()
2 process 908 0x00000000 in ?? ()
* 1 process 907 0x4a6e2238 in raise () from /lib/libc.so.6
You can found that the pc of 909 and 908 is 0x00000000.
With the patch:
(gdb) info threads
3 process 885 0x4a749974 in nanosleep () from /lib/libc.so.6
2 process 884 0x4a749974 in nanosleep () from /lib/libc.so.6
* 1 process 883 0x4a6e2238 in raise () from /lib/libc.so.6

Subject: [PATCH 0778/1002] mm: mark page accessed before we write_end()
In testing a backport of the write_begin/write_end AOPs, a 10% re-read
regression was noticed when running iozone. This regression was
introduced because the old AOPs would always do a mark_page_accessed(page)
after the commit_write, but when the new AOPs where introduced, the only
place this was kept was in pagecache_write_end().
This patch does the same thing in the generic case as what is done in
pagecache_write_end(), which is just to mark the page accessed before we
do write_end().

Subject: [PATCH 0780/1002] drivers/video/s3c-fb.c: fix clock setting for
Samsung SoC Framebuffer
Correct the CLKVAL_F field value of VIDEO MAIN CONTROLLER 0 REGITSTER.
Frame Rate is 1 / [ { (VSPW+1) + (VBPD+1) + (LIINEVAL + 1) + (VFPD+1)
} x {(HSPW+1) + (HBPD +1)
+ (HFPD+1) + (HOZVAL + 1) } x { ( CLKVAL+1 ) / ( Frequency of Clock
source ) } ] and VCLK = Video Clock Source / (CLKVAL +1).
therefore CLKVAL_F should be "CLKVAL_F = Frequency of Clock source / pixel
clock * refresh".
for this, I added refresh value in platform data like below.
static struct s3c_fb_pd_win xxx_fb_win0 = {
/* this is to ensure we use win0 */
.win_mode = {
.refresh = 60,
.pixclock = (66+4+2+480)*(15+5+3+800),
.left_margin = 66,
.right_margin = 2,
.upper_margin = 15,
.lower_margin = 3,
.hsync_len = 4,
.vsync_len = 5,
.xres = 480,
.yres = 800,
},
.max_bpp = 32,
.default_bpp = 24,
};
static struct s3c_fb_platdata xxx_lcd_pdata __initdata = {
.win[0] = &xxx_fb_win0,
.vidcon0 = VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB,
.vidcon1 = VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC
| VIDCON1_INV_VCLK | VIDCON1_INV_VDEN,
.setup_gpio = s5pc1xx_fb_gpio_setup_24bpp,
};
xxx_machine_init()
{
.
.
.
s3c_fb_set_platdata(&xxx_lcd_pdata);
}
platform data defined in machine code should be setting using
s3c_fb_set_platdata().

This is not right, change the code to return ERESTARTNOINTR.

Drivers that allocate their fb_info structure some other way (like
matrocfb's broken static allocation) need to be fixed up appropriately.

cpufreq
Commit b14893a62c73af0eca414cfed505b8c09efc613c although it was very
much needed to properly cleanup ondemand timer, opened-up a can of worms
related to locking dependencies in cpufreq.
Patch here defines the need for dbs_mutex and cleans up its usage in
ondemand governor. This also resolves the lockdep warnings reported here

Subject: [PATCH 0785/1002] [CPUFREQ] Mark policy_rwsem as going static in
cpufreq.c wont be exported
lock_policy_rwsem_* and unlock_policy_rwsem_* routines in cpufreq.c are
currently exported to drivers. Improper use of those locks can
result in deadlocks and it is better to keep the locks localized.
Two previous in-kernel users of these interfaces (ondemand and conservative),
do not use this interfaces any more. Schedule them for removal.

OK, I've tried to clean it up the best I could, but please test this with
concurrent cpu hotplug and cpufreq add/remove in loops. I'm sure we will make
other interesting findings.
This is step one of fixing the overall locking dependency mess in cpufreq.

fec: fix definition of 5272 version of FEC_X_DES_ACTIVE register
The ColdFire 5272 FEC driver has a different register address map
than other users of the FEC driver. And its definition of the
FEC_X_DES_ACTIVE register is incorrect, it should be 0x14.
The fec interface cannot transmit data with the old value.

Subject: [PATCH 0796/1002] UBI: fix NOR flash recovery
This commit fixes NOR flash recovery issues observed with Spansion
S29GL512N NOR.
When NOR erases, it first fills PEBs with zeroes, then sets all bytes
to 0xFF. Filling with zeroes starts from the end of the PEB. And when
power is cut, this results in PEBs containing correct EC and VID headers
but corrupted with zeros at the end. This confuses UBI and it mistakinly
accepts these PEBs and associate them with LEBs.
Fis this issue by zeroing EC and VID magics before erasing PEBs, to
make UBI later refuse zem.

Subject: [PATCH 0802/1002] [S390] udelay: disable lockdep to avoid false
positives
Our udelay implementation enables interrupts to receive a special timer
interrupt regardless of the context it is called from.
This might lead to false positive lockdep reports. Since lockdep isn't
aware of the fact that only a single interrupt source is enabled it
warns about possible deadlocks that in reality won't happen, like
the one below.
To fix this disable lockdep before enabling interrupts.

Subject: [PATCH 0804/1002] [S390] shutdown actions: save/return rc from init
function
We always returned -EINVAL when setting of a shutdown action failed. This was
misleading, if for example the hardware did not support the shutdown action.
Now we save each shutdown action's init return code and return it when the
action is being set.

The native implementation follows with the next kernel.

Subject: [PATCH 0811/1002] quota: Fix possible deadlock during parallel
quotaon and quotaoff
The following test script triggers a deadlock on ext2 filesystem:
while true; do quotaon /dev/hda >&/dev/null; usleep $RANDOM; done &
while true; do quotaoff /dev/hda >&/dev/null; usleep $RANDOM; done &
I found there is a potential deadlock between quotaon and quotaoff (or
quotasync). Basically, all of quotactl operations need to be protected by
dqonoff_mutex. vfs_quota_off and vfs_quota_sync also call sb->s_op->quota_write
that needs to grab the i_mutex of the quota file. But in vfs_quota_on_inode
(called from quotaon operation), the current code tries to grab the i_mutex of
the quota file first before getting quonoff_mutex.
Reverse the order in which we take locks in vfs_quota_on_inode().
Jan Kara: Changed changelog to be more readable, made lockdep happy with
I_MUTEX_QUOTA.

Subject: [PATCH 0812/1002] ALSA: hda - Fix capture source selection in
patch_via.c
The fixed widget NIDs in patch_via.c seem wrong for some codecs,
and it resulted in the invalid capture source selection.
This patch adds the code to parse the topology instead of using
fixed numbers in order to get the right MUX widget id corresponding
to the ADCs.

Fix condition in which radio LED did not initialize correctly, and remove
4 compilation warnings.
After the recent changes in rfkill, the radio LED used by b43/b43legacy
did not always initialize correctly.
Both b43 and b43legacy used the deprecated variable radio_enabled in
struct ieee80211_conf.

Subject: [PATCH 0815/1002] ath9k: Fix leak in tx descriptor
When we reclaim the tx desc, we always assume that the
last desc is a holding desc, which is not true, and skip it.
If the tx queue is drained during channel change, internal
reset and etc, the last descriptor may not be the holding
descriptor and we fail to reclaim them. This results in the
following two issues.
1. Tx stuck - We drop all the frames coming from upper layer
due to shortage in tx desc.
2. Crash - If we fail to reclaim a tx descriptor, we miss to
update the tx BA window with the seq number of the frame
associated to that desc, which, at some point, result in
the following crash due to an assert failure in ath_tx_addto_baw().
This patch fixes these two issues.

If rix is not found in mi->r[], i will become -1 after the loop. This value
is eventually used to access arrays, so we were accessing arrays with a
negative index, which is obviously not what we want to do. This patch fixes
this potential problem.

Usually crt mainly get modes via GPIOA ports.
However on G4X platform we need to probe possible
ports for DVI-I, which could be wired to GPIOD,
then fetch our desired EDID, i.e on DG45ID platform
we successfully fetch EDID by GPIOD port.
It fixed freedesktop.org bug #21084

Subject: [PATCH 0836/1002] powerpc: Fix spin_event_timeout() to be robust over
context switches
Current implementation of spin_event_timeout can be interrupted by an
IRQ or context switch after testing the condition, but before checking
the timeout. This can cause the loop to report a timeout when the
condition actually became true in the middle.
This patch adds one final check of the condition upon exit of the loop
if the last test of the condition was still false.

Subject: [PATCH 0839/1002] Input: mark serio and i8042 as suspended when
hibernating too
Serio ports are not being restarted any longer because resume operations
after hibernate do nothing, since the device has not been marked as
suspended. This happens because suspend is only considering the SUSPEND
event but not the FREEZE event.
Note that this driver has still to migrate to dev_pm_ops, but this fixes
this particular bug now.

only
HDA driver disabled HD audio 64bit address support for all AMD
SB600/SB700/SB800 platforms with commit
09240cf429505891d6123ce14a29f58f2a60121e due to one SB600 issue
reported by community, but we do not see the similar issue on
SB700/SB800 platforms.
This patch is to refine the workaround for SB600 only.

CONFIG_CC_STACKPROTECTOR
Patch 08687aec71bc9134fe336e561f6did877bacf74fc0a (x86: unify
power/cpu_(32|64).c) renamed cpu_32.c to cpu.c, but did not update
the special compilation flags for the file for the new name.
This patch fixes the compilation flags, and therefore fixes resume
from suspend on my Acer Aspire One.

There is a regression, introduced in aa202455eec51699e44f658530728162cefa1307
(in alsa-kernel) which I noticed when trying to use the headphone socket on

This patch corrects the control types to that which was obviously intended in
the referenced commit.

Fix various silly problems wrt mnt_namespace.h:
- exit_mnt_ns() isn't used, remove it
- done that, sched.h and nsproxy.h inclusions aren't needed
- mount.h inclusion was need for vfsmount_lock, but no longer
- remove mnt_namespace.h inclusion from files which don't use anything
from mnt_namespace.h

Subject: [PATCH 0855/1002] Free struct device in fw_dev_release()
The f_dev in _request_firmware() is allocated via the fw_setup_device()
and fw_register_device() calls and its class set to firmware_class (the
class release function is fw_dev_release).
Commit 6acf70f078ca replaced the kfree(dev) in fw_dev_release() with a
put_device() call but my understanding is that the release function is
called via put_device -> kobject_put -> kref_put -> koject_release etc.
and it should call kfree since it's the last to see this device
structure alive.
Because of that, the _request_firmware() function on its -ENOENT error
path only calls device_unregister(f_dev) which would eventually call
fw_dev_release() but there is no kfree (the subsequent put_device call
would just make the kref negative).

After some API change, intel_iommu_unmap_range() introduced a assumption that

overflowed argument. But the user like KVM don't have this assumption before,
then some BUG() triggered.
Fix it by ignoring size = 0.

This fixes the ppp problems and various other issues with call locking
caused by one side of a pty called in one locking context trying to match
another with differing rules on the other side. We also get a big slack
space to work with that means we can bury the flow control deadlock case
for any conceivable real world situation.

Alex found that specjbb2005 still can not run with hugepages on an
x86-64 machine. This only happens when numa is not compiled in.
The root cause: node_set_state will not set it back for us in that case,
so don't clear that when numa is not select in config
[ v2: use node_clear_state instead ]

It seems, the current threshold for root resizing is too aggressive,
and it causes misleading warnings during big updates, but it might be
also responsible for memory problems, especially with non-preempt
configs, when RCU freeing is delayed long after call_rcu.
It should be also mentioned that because of non-atomic changes during
resizing/rebalancing the current lookup algorithm can miss valid leaves
so it's additional argument to shorten these activities even at a cost
of a minimally longer searching.
This patch restores values before the patch "[IPV4]: fib_trie root
node settings", commit: 965ffea43d4ebe8cd7b9fee78d651268dd7d23c5 from
v2.6.22.

According to this and other similar reports average depth is slightly
increased (~0.2), and root nodes are shorter (log 17 vs. 18), but
there is no visible performance decrease. So, until memory handling is
improved or added parameters for changing this individually, this
patch resets to safer defaults.

On a shuttle machine here we got 07b8:6001 device, handled by zd1211rw, which does not work.
Scanning is OK but association does not work, we get "direct probe to AP xxx timed out"
It appears that this simple patch makes the device work perfectly.
This id was already there in initial import of the driver so I don't know if it has ever been
working as ZD1211 (which would mean they changed it and kept the id :( ).

There's a race condition -- started can be set to true
before channel is set due to the way mac80211 callbacks
currently work (->start should probably pass the channel
we would like to have initially). For now simply add a
check to hwsim to avoid dereferencing the NULL channel
pointer.

Subject: [PATCH 0872/1002] Atheros Kconfig needs to be dependent on WLAN_80211
Atheros top level menu needs a "depends WLAN_80211" to properly indent
within menuconfig and xconfig interfaces.
This is purely a visual issue but it effects all subsequent drivers.
The issue is the top level menu does not include a dependency on
WLAN_80211 so within the tree structure, Atheros is at the same level as
WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with
all subsequent drives, so it is really a subordinate.

Subject: [PATCH 0873/1002] p54: tx refused but queue active
In the mainline kernel, p54usb will fail because the TX queue length can
become < 0. This problem has been reported as Bugzilla #13725. The failure
is expressed by the following message in the logs:
WARNING: at net/mac80211/tx.c:1325 ieee80211_tx+0x23c/0x298 [mac80211]()
Hardware name: HP Pavilion dv2700 Notebook PC
tx refused but queue active
This problem has been recently observed in the wireless-testing tree, where
a full solution is being tested. That fix is too invasive for 2.6.31-rcX,
but the simple change supplied here will prevent the failure.

Subject: [PATCH 0880/1002] netpoll: Fix carrier detection for drivers that are
using phylib
Using early netconsole and gianfar driver this error pops up:
netconsole: timeout waiting for carrier
It appears that net/core/netpoll.c:netpoll_setup() is using
cond_resched() in a loop waiting for a carrier.
The thing is that cond_resched() is a no-op when system_state !=
SYSTEM_RUNNING, and so drivers/net/phy/phy.c's state_queue is never
scheduled, therefore link detection doesn't work.
I belive that the main problem is in cond_resched()[1], but despite
how the cond_resched() story ends, it might be a good idea to call
msleep(1) instead of cond_resched(), as suggested by Andrew Morton.

Subject: [PATCH 0881/1002] UBIFS: dump a little more in case of corruptions
In case of corruptions, dump 8192 bytes instead of 4096. The
largest node is 4096+ bytes, so it is better to see a node
boundary, which is not always possible when only 4096 bytes
are printed.

Subject: [PATCH 0882/1002] UBIFS: small amendments in the LEB scanning code
This patch fixes few minor things I've spotted while going through
code:
1. Better document return codes
2. If 'ubifs_scan_a_node()' returns some thing we do not expect,
treat this as an error.
3. Try to do recovery only when 'ubifs_scan()' returns %-EUCLEAN,
not on any error.
4. If empty space starts at a non-aligned address, print a message.

Subject: [PATCH 0884/1002] UBIFS: fix corruption dump
In the 'ubifs_recover_leb()' function, when we find corrupted
empty space, we dump 8K starting from the offset where the last
node ends. This is OK if the corrupted empty space is somewhere
near that offset. But if the corruption is far at the end of the
LEB, we will dump all 0xFF bytes and complitely ignore the
interesting data. This is observed on a PPC ("kilauea") with
NOR flash.
This patch changes the behavior and teaches UBIFS to print only
interesting data. I.e., now we find where corruption starts and
start dumping from that offset.

Subject: [PATCH 0886/1002] [ARM] 5577/2: ep93xx: syscon locked register
functions
Add core functions to handle writes to the ep93xx software locked
registers.
There are a number of registers in the EP93xx System Controller
that require a write to the software lock register before they
can be updated. This patch adds a number of exported functions
to the ep93xx core that handle this access.
The software locked clock divider registers, VidClkDiv, MIRClkDiv,
I2SClkDiv and KeyTchClkDiv would typically involve writing a
specific value to the register. To support this the
ep93xx_syscon_swlocked_write() function is provided.
For the DeviceCfg register it's more typical to only need to
set or clear a single bit. A generic ep93xx_devcfg_set_clear()
function is provided to handle both operations. Two inline
functions, ep93xx_devcfg_set_bits() and ep93xx_devcfg_clear_bits()
are also provided to improve code readability.
In addition, the remaining bits in the System Controller Device
Config Register have been documented and the previously defined
names shortened.
All code paths that use this functionality have been updated
except for arch/arm/kernel/crunch.c. That code is in a context
switch path, which is not reentrant, so it is safe against itself.

Subject: [PATCH 0887/1002] [ARM] 5578/1: ep93xx: add ep93xx-keypad clock
Add clkdev support for the ep93xx_keypad driver.
A matrix keypad driver for the ep93xx just got merged via the
input subsystem group. For this driver to work the keypad clock
needs to be added to the ep93xx clkdev support. In order to
accomplish this the following changes are implemented:
1) Move the EP93XX_EXT_*_RATE defines to mach/include/hardware.h.
2) Add EP93XX_KEYTCHCLK_DIV{4/16} for the keypad driver.
3) Add support for programmable clocks (set_rate() callback).
4) Add clk_keypad for the keypad driver.
5) tab indent the clk_lookup table for easier reading.
6) Add the set_rate() callback to program the keypad clock.
This callback is generalized since the ADC clock (touchscreen)
can use the same callback.
7) Use the ep93xx_syscon_swlocked_write() core function for updating
the software locked register.

Subject: [PATCH 0888/1002] [ARM] 5592/1: ep93xx: cleanup platform header
includes
arch/arm/mach-ep93xx/include/mach/hardware.h
1. Properly name the include files so that they are loaded
from the <mach/*> directory and not the local directory.
2. Remove including the ts72xx.h header. This header is not
generic to the ep93xx platform. It should only be included
by the ts72xx specific files that require it. The only
two users in the tree are arch/arm/mach-ep93xx/ts72xx.c
and drivers/mtd/nand/ts7250.c.
arch/arm/mach-ep93xx/include/mach/ts72xx.h
1. <linux/io.h> should already be included by any user of this
header. Doing the include here hides it from being needed
by the calling source file.
arch/arm/mach-ep93xx/core.c
1. Remove unnecessary headers. They were probably included
originally due to cut-and-paste from other files.
2. <linux/io.h> should be included not <mach/gpio.h>
arch/arm/mach-ep93xx/adsphere.c
arch/arm/mach-ep93xx/edb93xx.c
arch/arm/mach-ep93xx/gesbc9312.c
arch/arm/mach-ep93xx/micro9.c
arch/arm/mach-ep93xx/ts72xx.c
1. Remove unnecessary headers.
arch/arm/mach-ep93xx/ts72xx.c
1. Remove unnecessary headers.
2. Add platform specific header <mach/ts72xx.h>.
drivers/mtd/nand/ts7250.c
1. <linux/io.h> should be included not <asm/io.h>.
2. Add platform specific header <mach/ts72xx.h>.

This patch replaces the hardcoded 255 seconds limit for a real limit based on

Also, the 'firmware_version' field is changed to '1' to allow the user
space application to easily detect that this driver supports a higher
maximum timeout.

cifs: add and use CIFSSMBUnixSetFileInfo for setattr calls
When there's an open filehandle, SET_FILE_INFO is apparently preferred
over SET_PATH_INFO. Add a new variant that sets a FILE_UNIX_INFO_BASIC
infolevel via SET_FILE_INFO and switch cifs_setattr_unix to use the
new call when there's an open filehandle available.

Subject: [PATCH 0903/1002] drm/i915: Check the LID device to decide whether
the LVDS should be initialized
On some boxes the mobile chipset is used and there is no LVDS device. In such
case we had better not initialize the LVDS output device so that one pipe can
be used for other output device. For example: E-TOP.
But unfortunately the LVDS device is still initialized on the boxes based on
mobile chipset in KMS mode. It brings that this pipe occupied by LVDS can't be
used for other output device.
After checking the acpidump we find that there is no LID device on such boxes.
In such case we can use the LID device to decide whether the LVDS device should
be initialized.
If there is no LID device, we can think that there is no LVDS device. It is
unnecessary to initialize the LVDS output device.
If there exists the LID device, it will continue the current flowchart.
Maybe on some boxes there is no LVDS device but the LID device is found. In
such case it should be added to the quirk list.

Subject: [PATCH 0904/1002] cifs: convert cifs_get_inode_info and non-posix

cifs: convert cifs_get_inode_info and non-posix readdir to use cifs_iget
Rather than allocating an inode and filling it out, have
cifs_get_inode_info fill out a cifs_fattr and call cifs_iget. This means
a pretty hefty reorganization of cifs_get_inode_info.
For the readdir codepath, add a couple of new functions for filling out
cifs_fattr's from different FindFile response infolevels.
Finally, remove cifs_new_inode since there are no more callers.

cifs: when ATTR_READONLY is set, only clear write bits on non-directories
On windows servers, ATTR_READONLY apparently either has no meaning or

behavior. This MS kbase article has details:
http://support.microsoft.com/kb/326549/
Don't clear the write bits directory mode when ATTR_READONLY is set.

Subject: [PATCH 0907/1002] net: adding memory barrier to the poll and receive
callbacks
Adding memory barrier after the poll_wait function, paired with
receive callbacks. Adding fuctions sock_poll_wait and sk_has_sleeper
to wrap the memory barrier.
Without the memory barrier, following race can happen.
The race fires, when following code paths meet, and the tp->rcv_nxt
and __add_wait_queue updates stay in CPU caches.
CPU1 CPU2
sys_select receive packet
... ...
__add_wait_queue update tp->rcv_nxt
... ...
tp->rcv_nxt check sock_def_readable
... {
schedule ...
if (sk->sk_sleep && waitqueue_active(sk->sk_sleep))
wake_up_interruptible(sk->sk_sleep)
...
}
If there was no cache the code would work ok, since the wait_queue and
rcv_nxt are opposit to each other.
Meaning that once tp->rcv_nxt is updated by CPU2, the CPU1 either already
passed the tp->rcv_nxt check and sleeps, or will get the new value for
tp->rcv_nxt and will return with new data mask.
In both cases the process (CPU1) is being added to the wait queue, so the
waitqueue_active (CPU2) call cannot miss and will wake up CPU1.
The bad case is when the __add_wait_queue changes done by CPU1 stay in its
cache, and so does the tp->rcv_nxt update on CPU2 side. The CPU1 will then
endup calling schedule and sleep forever if there are no more data on the
socket.
Calls to poll_wait in following modules were ommited:
net/bluetooth/af_bluetooth.c
net/irda/af_irda.c
net/irda/irnet/irnet_ppp.c
net/mac80211/rc80211_pid_debugfs.c

Subject: [PATCH 0909/1002] ixgbe: Fix coexistence of FCoE and Flow Director in
82599
Fix coexistence of Fiber Channel over Ethernet (FCoE) and Flow Director (FDIR)
in 82599 and remove the disabling of FDIR when FCoE is enabled.
Currently, FDIR is turned off when FCoE is enabled under the assumption that
FCoE is always enabled with DCB being turned on. However, FDIR does not have
to be turned off all the time when FCoE is enabled since FCoE can be enabled
without DCB being turned on, e.g., use link pause only. This patch makes sure
that when DCB is turned on or off, FDIR is turned on or off correspondingly;
and when FCoE is enabled, it does not disable FDIR, rather, it will have FDIR
set up properly so FCoE and FDIR can coexist regardless of DCB being on or off.

Subject: [PATCH 0910/1002] cxgb3: Fix crash caused by stashing wrong
netdev_queue
Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how
cxgb3 looks up the netdev_queue it stashes away in a qset during
initialization. For multiport devices, the TX queue index it uses is
offset by the first_qset index of each port. This leads to a crash
once LLTX is removed, since hard_start_xmit is called with one TX
queue lock held, while the TX reclaim timer task grabs a different
(wrong) TX queue lock when it frees skbs.
Fix this by removing the first_qset offset used to look up the TX
queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

Subject: [PATCH 0917/1002] block: call blk_scsi_ioctl_init()
Currently, blk_scsi_ioctl_init() is not called since it lacks
an initcall marking. This causes the command table to be
unitialized, hence somce commands are block when they should
not have been.
This fixes a regression introduced by commit

Subject: [PATCH 0918/1002] block: fix sg SG_DXFER_TO_FROM_DEV regression
I overlooked SG_DXFER_TO_FROM_DEV support when I converted sg to use
the block layer mapping API (2.6.28).
Douglas Gilbert explained SG_DXFER_TO_FROM_DEV:
http://www.spinics.net/lists/linux-scsi/msg37135.html
=
The semantics of SG_DXFER_TO_FROM_DEV were:
- copy user space buffer to kernel (LLD) buffer
- do SCSI command which is assumed to be of the DATA_IN
(data from device) variety. This would overwrite
some or all of the kernel buffer
- copy kernel (LLD) buffer back to the user space.
The idea was to detect short reads by filling the original
user space buffer with some marker bytes ("0xec" it would
seem in this report). The "resid" value is a better way
of detecting short reads but that was only added this century
and requires co-operation from the LLD.
=
This patch changes the block layer mapping API to support this
semantics. This simply adds another field to struct rq_map_data and
enables __bio_copy_iov() to copy data from user space even with READ
requests.
It's better to add the flags field and kills null_mapped and the new
from_user fields in struct rq_map_data but that approach makes it
difficult to send this patch to stable trees because st and osst
drivers use struct rq_map_data (they were converted to use the block
layer in 2.6.29 and 2.6.30). Well, I should clean up the block layer
mapping API.
zhou sf reported this regiression and tested this patch:

Subject: [PATCH 0919/1002] cfq-iosched: reset oom_cfqq in cfq_set_request()
In case memory is scarce, we now default to oom_cfqq. Once memory is
available again, we should allocate a new cfqq and stop using oom_cfqq for
a particular io context.
Once a new request comes in, check if we are using oom_cfqq, and if yes,
try to allocate a new cfqq.
Tested the patch by forcing the use of oom_cfqq and upon next request thread
realized that it was using oom_cfqq and it allocated a new cfqq.

Subject: [PATCH 0920/1002] drm/i915: Disable GEM when a broken video BIOS
takes up the whole aperture.
This is seen on some G41 systems, where the BIOS will consume all but
a few KB of the aperture. This should be bad for all operating systems, as
it means that the OS can't dynamically manage memory between graphics and
the rest of the system, and OSes that did static memory management
statically add memory in addition to the BIOS allocation anyway. So, instead
of working around it, just fail out verbosely.

Subject: [PATCH 0925/1002] dma-debug: Fix the overlap() function to be correct
and readable
Linus noticed how unclean and buggy the overlap() function is:
- It uses convoluted (and bug-causing) positive checks for
range overlap - instead of using a more natural negative
check.
- Even the positive checks are buggy: a positive intersection
check has four natural cases while we checked only for three,
missing the (addr < start && addr2 == end) case for example.
- The variables are mis-named, making it non-obvious how the
check was done.
- It needlessly uses u64 instead of unsigned long. Since these
are kernel memory pointers and we explicitly exclude highmem
ranges anyway we cannot ever overflow 32 bits, even if we
could. (and on 64-bit it doesnt matter anyway)
All in one, this function needs a total revamp. I used Linus's
suggestions minus the paranoid checks (we cannot overflow really
because if we get totally bad DMA ranges passed far more things
break in the systems than just DMA debugging). I also fixed a
few other small details i noticed.

Subject: [PATCH 0927/1002] drm/i915: Zap the GTT mapping when transitioning
from untiled to tiled.
As of 52dc7d32b88156248167864f77a9026abe27b432, we could leave an old
linear GTT mapping in place, so that apps trying to GTT-mapped write in
tiled data wouldn't get the fence added, and garbage would get displayed.

Subject: [PATCH 0929/1002] sched: INIT_PREEMPT_COUNT
Pull the initial preempt_count value into a single
definition site.
Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.
The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

Subject: [PATCH 0930/1002] sched: optimize cond_resched()
Optimize cond_resched() by removing one conditional.
Currently cond_resched() checks system_state ==
SYSTEM_RUNNING in order to avoid scheduling before the
scheduler is running.
We can however, as per suggestion of Matt, use
PREEMPT_ACTIVE to accomplish that very same.

Subject: [PATCH 0933/1002] Doc: move Documentation/exception.txt into x86
subdir
exception.txt only explains the code on x86, so it's better to
move it into Documentation/x86 directory.
And also rename it to exception-tables.txt which looks much
more reasonable.
This patch is on top of the previous one.

Subject: [PATCH 0940/1002] [ARM] remove L_PTE_BUFFERABLE and L_PTE_CACHEABLE
These old symbols are meaningless now that we have memory type
support implemented. The entire memory type field needs to be
modified rather than just a few bits twiddled.

Subject: [PATCH 0941/1002] [ARM] pgtable: rearrange file PTE bit allocation
For future compatibility, we need to ensure that swap and file Linux
PTEs conform with the hardware PTEs "fault" encoding. Swap PTEs
already fit in with this, but file PTEs do not. Shift them by one
bit to ensure that they conform, using bit 2 to distinguish between
swap and file PTEs.

Subject: [PATCH 0944/1002] [ARM] 5600/1: ep93xx: core.c remove cast when
copying dev_addr
The MAC address for the ep93xx ethernet driver can be optionally
copied from registers in the controller when booting. Due to
[ARM] 5573/1: ep93xx: ensure typesafe io, the cast for the source
address is no longer needed.
EP93XX_ETHERNET_BASE is typed as a (void __iomem __force *) so
memcpy_fromio() needs to be used instead of memcpy().

Subject: [PATCH 0951/1002] [ARM] 5612/1: ep93xx: add platform LEDs
The EP93xx has two gpio pins specifically assigned to drive
external LEDs. Add core support for these LEDs.
On the EDB93xx development boards, the rdled is connected to
an external reset circuit. Turning this led on for an extended
amount of time will cause the circuit to issue a manual reset.
Refer to Cirrus App Note AN258 for more information.
http://www.cirrus.com/en/pubs/appNote/AN258REV2.pdf
This led can be safely used as the system heartbeat with the
ledtrig-heartbeat driver.
echo heartbeat > /sys/class/leds/platform:rdled/trigger
The grled can be used for any desired purpose.

Subject: [PATCH 0952/1002] [ARM] 5613/1: implement CALLER_ADDRESSx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
As __builtin_return_address(n) doesn't work for ARM with n > 0, the
kernel needs its own implementation.
This fixes many warnings saying:
warning: unsupported argument to '__builtin_return_address'
The new methods and walk_stackframe must not be instrumented because
CALLER_ADDRESSx is used in the various tracers and tracing the tracer is
a bad idea.
What's currently missing is an implementation using unwind tables. This
is not fatal though, it's just that the tracers don't get enough
information to be really useful.
Note that if both ARM_UNWIND and FRAME_POINTER are enabled,
walk_stackframe uses unwind information. So in this case the same
implementation is used as when FRAME_POINTER is disabled.

Subject: [PATCH 0960/1002] ARM: 5628/1: ep93xx: Introduce Pulse Width
Modulator (PWM) driver
The EP93xx features two PWMs (one on the EP9307) with the following
features:
* Configurable dual output
* Separate input clocks for each PWM output
* 16-bit resolution
* Programmable pulse width (duty cycle), interval (frequency), and
polarity
This adds the necessary core support as well as the driver. A sysfs
interface is provided to control the PWM outputs.

Subject: [PATCH 0969/1002] ARM: 5677/1: ARM support for
TIF_RESTORE_SIGMASK/pselect6/ppoll/epoll_pwait
This patch adds support for TIF_RESTORE_SIGMASK to ARM's
signal handling, which allows to hook up the pselect6, ppoll,
and epoll_pwait syscalls on ARM.
Tested here with eabi userspace and a test program with a
deliberate race between a child's exit and the parent's
sigprocmask/select sequence. Using sys_pselect6() instead
of sigprocmask/select reliably prevents the race.
The other arch's support for TIF_RESTORE_SIGMASK has evolved
over time:
In 2.6.16:
- add TIF_RESTORE_SIGMASK which parallels TIF_SIGPENDING
- test both when checking for pending signal [changed later]
- reimplement sys_sigsuspend() to use current->saved_sigmask,
TIF_RESTORE_SIGMASK [changed later], and -ERESTARTNOHAND;
ditto for sys_rt_sigsuspend(), but drop private code and
use common code via __ARCH_WANT_SYS_RT_SIGSUSPEND;
- there are now no "extra" calls to do_signal() so its oldset
parameter is always ¤t->blocked so need not be passed,
also its return value is changed to void
- change handle_signal() to return 0/-errno
- change do_signal() to honor TIF_RESTORE_SIGMASK:
+ get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
is set
+ if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
+ if no signal was delivered and TIF_RESTORE_SIGMASK is set then
clear it and restore the sigmask
- hook up sys_pselect6() and sys_ppoll()
In 2.6.19:
- hook up sys_epoll_pwait()
In 2.6.26:
- allow archs to override how TIF_RESTORE_SIGMASK is implemented;
default set_restore_sigmask() sets both TIF_RESTORE_SIGMASK and
TIF_SIGPENDING; archs need now just test TIF_SIGPENDING again
when checking for pending signal work; some archs now implement
TIF_RESTORE_SIGMASK as a secondary/non-atomic thread flag bit
- call set_restore_sigmask() in sys_sigsuspend() instead of setting
TIF_RESTORE_SIGMASK
In 2.6.29-rc:
- kill sys_pselect7() which no arch wanted
So for 2.6.31-rc6/ARM this patch does the following:
- Add TIF_RESTORE_SIGMASK. Use the generic set_restore_sigmask()
which sets both TIF_SIGPENDING and TIF_RESTORE_SIGMASK, so
TIF_RESTORE_SIGMASK need not claim one of the scarce low thread
flags, and existing TIF_SIGPENDING and _TIF_WORK_MASK tests need
not be extended for TIF_RESTORE_SIGMASK.
- sys_sigsuspend() is reimplemented to use current->saved_sigmask
and set_restore_sigmask(), making it identical to most other archs
- The private code for sys_rt_sigsuspend() is removed, instead
generic code supplies it via __ARCH_WANT_SYS_RT_SIGSUSPEND.
- sys_sigsuspend() and sys_rt_sigsuspend() no longer need a pt_regs
parameter, so their assembly code wrappers are removed.
- handle_signal() is changed to return 0 on success or -errno.
- The oldset parameter to do_signal() is now redundant and removed,
and the return value is now also redundant and changed to void.
- do_signal() is changed to honor TIF_RESTORE_SIGMASK:
+ get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
is set
+ if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
+ if no signal was delivered and TIF_RESTORE_SIGMASK is set then
clear it and restore the sigmask
- Hook up sys_pselect6, sys_ppoll, and sys_epoll_pwait.

Subject: [PATCH 0996/1002] ARM: implement highpte
Add the ARM implementation of highpte, which allows PTE tables to be
placed in highmem. Unfortunately, we do not offer highpte support
when support for L2 cache is enabled.

Subject: [PATCH 0997/1002] ARM: 5682/1: Add cpu.c and dev.c and modify some
files of w90p910 platform
Add the cpu.c and dev.c and modify w90p910 platform
to apply to use the common API(provided by cpu.c and dev.c)
at the same time, I renamed all w90x900 to nuc900 in every
c file of w90x900 platform and touchscreen's driver name.
