  arm64: cputype: Silence Sparse warnings (2018-02-17 08:37:05 +0000)

----------------------------------------------------------------
arm64 fixes:

- Updated the page table accessors to use READ/WRITE_ONCE and prevent
  compiler transformation that could lead to an apparent loss of
  coherency

- Enabled branch predictor hardening for the Falkor CPU

- Fix interaction between kpti enabling and KASan causing the recursive
  page table walking to take a significant time

- Fix some sparse warnings
