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