Hi Linus,
Please pull the arm64 fixes below. The bulk of this pull request is the
pte accessors annotation to READ/WRITE_ONCE (we tried to avoid pushing
this during the merging window to avoid conflicts). Thanks.

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
