Paolo Bonzini 6d5e3c318a KVM x86 changes for 6.6:
- Misc cleanups
 
  - Retry APIC optimized recalculation if a vCPU is added/enabled
 
  - Overhaul emergency reboot code to bring SVM up to par with VMX, tie the
    "emergency disabling" behavior to KVM actually being loaded, and move all of
    the logic within KVM
 
  - Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC
    ratio MSR can diverge from the default iff TSC scaling is enabled, and clean
    up related code
 
  - Add a framework to allow "caching" feature flags so that KVM can check if
    the guest can use a feature without needing to search guest CPUID
