Pull more arm64 updates from Catalin Marinas:
 "These are some some trivial updates that mostly fix/clean-up code
  pushed during the merging window:

   - Work around broken GCC 4.9 handling of "S" asm constraint

   - Suppress W=1 missing prototype warnings

   - Warn the user when a small VA_BITS value cannot map the available
     memory

   - Drop the useless update to per-cpu cycles"
