Pull arm64 fixes from Will Deacon:
 "Small crop of relatively boring arm64 fixes for -rc3.

  That's not to say we don't have any juicy bugs, however, it's just
  that fixes for those are likely to come via -mm and -tip for a hugetlb
  and an atomics issue respectively. I get left with the
  documentation...

   - Fix detection of "ClearBHB" and "Hinted Conditional Branch" features

   - Fix broken wildcarding for Arm PMU MAINTAINERS entry

   - Add missing documentation for userspace-visible ID register fields"
