    Linus Torvalds authored
    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"
