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

Pull arm64 fixes from Catalin Marinas:
 "These are primarily bug fixes with a performance improvement patch for
  the GHASH crypto algorithm (which went in during this merging window)
  and dts/defconfig/Kconfig updates.

   - ftrace_return_addr() macro fix for arm (introduced earlier via the
     arm64 tree)
   - stack alignment exception entry code fix
   - GHASH crypto algorithm fix and performance improvement
   - CMA buffer limited to 32-bit (until a better way to describe the
     system topology in DT)
   - UAPI sigcontext.h build fix
   - __kernel_old_{gid,uid}_t definitions fix (affecting 32-bit LTP)
   - ptrace fixes (kernel fault and 32-bit arm core dump)
   - pte_mknotpresent() fix
   - dts updates (APM SoC)
   - defconfig and Kconfig update"
