Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

commit 7fe28d7e68f92cc3d0668b8f2fbdf5c303ac3022 upstream. In all the vgic_its_save_*() functinos, they do not check whether the data length is 8 bytes before calling vgic_write_guest_lock. This patch adds the check. To prevent the kernel from being blown up when the fault occurs, KVM_BUG_ON() is used. And the other BUG_ON()s are replaced together.
