Pull arm64 fixes from Will Deacon:
 "Three arm64 fixes for -rc4.

  One of them is just a trivial documentation fix, whereas the other two
  address a warning in the kexec code and a crash in ftrace on systems
  implementing BTI.

  The latter patch has a couple of ugly ifdefs which Mark plans to clean
  up separately, but as-is the patch is straightforward for backporting
  to stable kernels.

  Summary:

   - Add missing BTI landing instructions to the ftrace*_caller
     trampolines

   - Fix kexec() WARN when DEBUG_VIRTUAL is enabled

   - Fix PAC documentation by removing stale references to compiler
     flags"

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.
