Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 fixes from Will Deacon:
 "The big one is a fix for the VHE enabling path during early boot,
  where the code enabling the MMU wasn't necessarily in the identity map
  of the new page-tables, resulting in a consistent crash with 64k
  pages. In fixing that, we noticed some missing barriers too, so we
  added those for the sake of architectural compliance.

  Other than that, just the usual merge window trickle. There'll be more
  to come, too.

  Summary:

   - Fix lockdep false alarm on resume-from-cpuidle path

   - Fix memory leak in kexec_file

   - Fix module linker script to work with GDB

   - Fix error code when trying to use uprobes with AArch32 instructions

   - Fix late VHE enabling with 64k pages

   - Add missing ISBs after TLB invalidation

   - Fix seccomp when tracing syscall -1

   - Fix stacktrace return code at end of stack

   - Fix inconsistent whitespace for pointer return values

   - Fix compiler warnings when building with W=1"

README

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 Restructured Text 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.
