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

Pull more arm64 fixes from Will Deacon:
 "Another handful of arm64 fixes here.  They address some issues found
  by running smatch on the arch code (ignoring the false positives) and
  also stop 32-bit Android from losing track of its stack.

  There's one additional irq migration fix in the pipeline, but it came
  in after I'd tagged and tested this set.

   - a few fixes for real issues found by smatch (after Dan's talk at KS)

   - revert the /proc/cpuinfo changes merged during the merge window.
     We've opened a can of worms here, so we need to find out where we
     stand before we change this interface.

   - implement KSTK_ESP for compat tasks, otherwise 32-bit Android gets
     confused wondering where its [stack] has gone

   - misc fixes (fpsimd context handling, crypto, ...)"
