Pull arm64 fixes from Will Deacon:
"Fix some more FP register fallout from the SVE patches and also some
problems with the PGD tracking in our software PAN emulation code,
after we received a crash report from a 3.18 kernel running a
backport.
Summary:
- fix SW PAN pgd shadowing for kernel threads, EFI and exiting user
tasks
- fix FP register leak when a task_struct is re-allocated
- fix potential use-after-free in FP state tracking used by KVM"

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
