Linus,

  KVM: x86: Set so called 'reserved CR3 bits in LM mask' at vCPU reset (2021-02-04 12:59:28 -0500)

----------------------------------------------------------------
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:
- "KVM: x86: Allow guests to see MSR_IA32_TSX_CTRL even if tsx=off"
  (live migration failure seen on distros that hadn't switched to tsx=off
  right away)

ARM:
- Avoid clobbering extra registers on initialisation
