Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 fixes from Will Deacon:
 "Here's a sizeable batch of Friday the 13th arm64 fixes for -rc4. What
  could possibly go wrong?

  The obvious reason we have so much here is because of the holiday
  season right after the merge window, but we've also brought back an
  erratum workaround that was previously dropped at the last minute and
  there's an MTE coredumping fix that strays outside of the arch/arm64
  directory.

  Summary:

   - Fix PAGE_TABLE_CHECK failures on hugepage splitting path

   - Fix PSCI encoding of MEM_PROTECT_RANGE function in UAPI header

   - Fix NULL deref when accessing debugfs node if PSCI is not present

   - Fix MTE core dumping when VMA list is being updated concurrently

   - Fix SME signal frame handling when SVE is not implemented by the
     CPU

   - Fix asm constraints for cmpxchg_double() to hazard both words

   - Fix build failure with stack tracer and older versions of Clang

   - Bring back workaround for Cortex-A715 erratum 2645198"
