Pull KVM fixes from Paolo Bonzini:
 "x86 has lots of small bugfixes, mostly one liners. It's quite late in
  5.11-rc but none of them are related to this merge window; it's just
  bugs coming in at the wrong time.

  Of note among the others is "KVM: x86: Allow guests to see
  MSR_IA32_TSX_CTRL even if tsx=off" that fixes a live migration failure
  seen on distros that hadn't switched to tsx=off right away.

  ARM:
  - Avoid clobbering extra registers on initialisation"

[ Sean Christopherson notes that commit 943dea8af21b ("KVM: x86: Update
  emulator context mode if SYSENTER xfers to 64-bit mode") should have
  had authorship credited to Jonny Barker, not to him.  - Linus ]
