Pull arm64 fixes from Will Deacon:
 "Given that my availability next week is likely to be poor, here are
  three arm64 fixes to resolve some issues introduced by features merged
  last week.  I was going to wait until -rc1, but it doesn't make much
  sense to sit on fixes.

  Fix some fallout introduced during the merge window:

   - Build failure when PM_SLEEP is disabled but CPU_IDLE is enabled
   - Compiler warning from page table dumper w/ 48-bit VAs
   - Erroneous page table truncation in reported dump"
