Pull arm64 fixes from Will Deacon:
 "In this batch we've got a couple of hibernation fixes, a couple of
  minor MTE fixes, some per-cpu codegen fixes (which were found as part
  of Mark's series adding preemptible this_cpu_*() operations) and a fix
  for the Arm CMN PMU driver.

  Summary:

   - Fix hypercall arguments when resetting EL2 vectors during
     hibernation

   - Fix hibernation with 52-bit capable kernels on machines without
     52-bit addressing, similarly to the recent kexec fix

   - Fix a bunch of clumsy codegen issues with our per-cpu accessors

   - Fix MTE ptrace documentation to reflect the de-facto ABI behaviour

   - Fix pthread_join() usage in MTE selftest

   - Fix port selection in the Arm CMN PMU driver"
