Pull arm64 fixes from Will Deacon:
 "It's a lot smaller than last week, with the star of the show being a
  couple of fixes to head.S addressing a boot regression introduced by
  the recent overhaul of that code in non-default configurations (i.e.
  KASLR disabled).

  The first of those two resolves the issue reported (and bisected) by
  Mikulus in the wait_on_bit() thread.

  Summary:

   - Fix two boot issues caused by the recent head.S rework when !KASLR

   - Fix calculation of crashkernel memory reservation

   - Fix bogus error check in PMU IRQ probing code"
