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

Pull arm64 fixes from Will Deacon:
 "The main thing here is reviving hugetlb support using contiguous ptes,
  which we ended up reverting at the last minute in 4.5 pending a fix
  which went into the core mm/ code during the recent merge window.

   - Revert a previous revert and get hugetlb going with contiguous hints
   - Wire up missing compat syscalls
   - Enable CONFIG_SET_MODULE_RONX by default
   - Add missing line to our compat /proc/cpuinfo output
   - Clarify levels in our page table dumps
   - Fix booting with RANDOMIZE_TEXT_OFFSET enabled
   - Misc fixes to the ARM CPU PMU driver (refcounting, probe failure)
   - Remove some dead code and update a comment"
