The freezer should not send signals to kernel threads, since that may lead to subtle problems. In particular, commit b74d0deb has changed recalc_sigpending_tsk() so that it doesn't clear TIF_SIGPENDING. For this reason, if the freezer continues to send fake signals to kernel threads and the freezing of kernel threads fails, some of them may be running with TIF_SIGPENDING set forever. Accordingly, recalc_sigpending_tsk() shouldn't set the task's TIF_SIGPENDING flag if TIF_FREEZE is set. Signed-off-by:

The name of 'struct pm_ops' suggests that it is related to the power management in general, but in fact it is only related to suspend. Moreover, its name should indicate what this structure is used for, so it seems reasonable to change it to 'struct platform_suspend_ops'. In that case, the name of the global variable of this type used by the PM core and the names of related functions should be changed accordingly. Signed-off-by:

The 9P2000 protocol requires the authentication and permission checks to be done in the file server. For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by:

Add missing IRQs and IRQ descriptions to /proc/interrupts. /proc/interrupts is most useful when it displays every IRQ vector in use by the system, not just those somebody thought would be interesting. This patch inserts the following vector displays to the i386 and x86_64 platforms, as appropriate: rescheduling interrupts TLB flush interrupts function call interrupts thermal event interrupts threshold interrupts spurious interrupts A threshold interrupt occurs when ECC memory correction is occuring at too high a frequency. Thresholds are used by the ECC hardware as occasional ECC failures are part of normal operation, but long sequences of ECC failures usually indicate a memory chip that is about to fail. Thermal event interrupts occur when a temperature threshold has been exceeded for some CPU chip. IIRC, a thermal interrupt is also generated when the temperature drops back to a normal level. A spurious interrupt is an interrupt that was raised then lowered by the device before it could be fully processed by the APIC. Hence the apic sees the interrupt but does not know what device it came from. For this case the APIC hardware will assume a vector of 0xff. Rescheduling, call, and TLB flush interrupts are sent from one CPU to another per the needs of the OS. Typically, their statistics would be used to discover if an interrupt flood of the given type has been occuring. AK: merged v2 and v4 which had some more tweaks AK: replace Local interrupts with Local timer interrupts AK: Fixed description of interrupt types.

Convert LSM into a static interface, as the ability to unload a security module is not required by in-tree users and potentially complicates the overall security architecture. Needlessly exported LSM symbols have been unexported, to help reduce API abuse. Parameters for the capability and root_plug modules are now specified at boot. The SECURITY_FRAMEWORK_VERSION macro has also been removed. In a nutshell, there is no safe way to unload an LSM. The modular interface is thus unecessary and broken infrastructure. It is used only by out-of-tree modules, which are often binary-only, illegal, abusive of the API and dangerous, e.g. silently re-vectoring SELinux.

A couple of updates haven't considered whether the documentation makes sense as a whole any more. Three changes here: - Remove the reference to the "DAC Addressing for Address Space Hungry Devices" section which was deleted by Jan Beulich. - Remove the comment about DMA_24BIT_MASK which became obsolete when Tobias Klauser changed the code to actually use DMA_24BIT_MASK. - Remove the section "64-bit DMA and DAC cycle support" since it's fully covered above, and contains a reference to the section deleted by Jan.

Remove the old-fashioned lk201 driver under drivers/tc/ that used to be used by the old dz.c and zs.c drivers, which is now orphan code referred to from nowhere and does not build anymore. A modern replacement is available as drivers/input/keyboard/lkkbd.c. There are no plans to do anything about this piece of code and it does not fit anywhere anymore, so it is not just a matter of maintenance or the lack of. There are still some bits that might be added to the new lkkbd.c driver based on the old code, and the embedded hardware documentation which is otherwise quite hard to get hold of might be useful to keep too. Both of these can be done separately though. RIP. Signed-off-by:
