[PATCH 0/2] KVM: x86: kvm_has_noapic_vcpu fix/cleanup

[Sean Christopherson <seanjc@google.com>]

Fix a longstanding bug where KVM fails to decrement kvm_has_noapic_vcpu
if vCPU creation ultimately fails.  This is obviously way more than just
a fix, but (a) in all likelihood no real users are affected by this, (b)
the absolutely worst case scenario is minor performance degredation, and
(c) I'm not at all convinced that kvm_has_noapic_vcpu provides any
performance benefits.

Sean Christopherson (2):
  KVM: x86: Move "KVM no-APIC vCPU" key management into local APIC code
  KVM: x86: Sanity check that kvm_has_noapic_vcpu is zero at
    module_exit()
