Merge tag 'arm64-fixes' of git://

Pull arm64 fixes from Will Deacon:
 "Catalin's out enjoying the sunshine, so I'm sending the fixes for a
  couple of weeks (although there hopefully won't be any more!).

  We've got a revert of a previous fix because it broke the build with
  some distro toolchains and a preemption fix when detemining whether or
  not the SIMD unit is in use.


   - Revert back to the 'linux' target for LD, as 'elf' breaks some

   - Fix preemption race when testing whether the vector unit is in use
     or not"
