Pull arm64 fixes from Will Deacon:
 "Three arm64 fixes for -rc8/final.

  The MTE and stolen time fixes have been doing the rounds for a little
  while, but review and testing feedback was ongoing until earlier this
  week. The kexec fix showed up on Monday and addresses a failure
  observed under Qemu.

  Summary:

   - Add missing write barrier to publish MTE tags before a pte update

   - Fix kexec relocation clobbering its own data structures

   - Fix stolen time crash if a timer IRQ fires during CPU hotplug"
