[0/3] KVM: x86: APICv inhibition cleanups

Message

Sean Christopherson March 11, 2022, 4:35 a.m. UTC

Refactor the APICv inhibition code to use small set/clear wrappers instead
of passing an impressively ambiguous "activate" boolean.  Opportunistically
enhance the related tracepoint so that debugging why a VM can't use APICv
is slightly less painful.

Sean Christopherson (3):
  KVM: x86: Make APICv inihibit reasons an enum and cleanup naming
  KVM: x86: Add wrappers for setting/clearing APICv inhibits
  KVM: x86: Trace all APICv inhibit changes and capture overall status
