Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 cpu-features updates from Ingo Molnar:
 "The biggest change in this cycle was a large series from Sean
  Christopherson to clean up the handling of VMX features. This both
  fixes bugs/inconsistencies and makes the code more coherent and
  future-proof.

  There are also two cleanups and a minor TSX syslog messages
  enhancement"
