#     Merge tag 'x86-pti-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 pti updates from Thomas Gleixner:
#      "The performance deterioration departement provides a few non-scary
#       fixes and improvements:
#     
#        - Update the cached HLE state when the TSX state is changed via the
#          new control register. This ensures feature bit consistency.
#     
#        - Exclude the new Zhaoxin CPUs from Spectre V2 and SWAPGS
#          vulnerabilities"
