  commit 6536688439dbca1d08fd6db5be29c39e3917fb2f
  Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>
  Date:   Wed Jan 12 13:52:47 2022 +0000
  
      x86/msr: Split MSR_SPEC_CTRL handling
      
      In order to fix a VT-x bug, and support MSR_SPEC_CTRL on AMD, move
      MSR_SPEC_CTRL handling into the new {pv,hvm}_{get,set}_reg() 
infrastructure.
      
      Duplicate the msrs->spec_ctrl.raw accesses in the PV and VT-x paths for 
now.
      The SVM path is currently unreachable because of the CPUID policy.
      
      No functional change.
