Subject: [PATCH 0/5] KVM: x86: Move apicv_active into kvm_lapic

Move apicv_active into struct kvm_lapic; KVM enables APICv if and only if
a VM/vCPU has an in-kernel APIC.

This was posted a while back as a one-off patch in an APICv cleanup[*].
The idea and most of the changes remain the same, though I eked out a few
more cleanups.

Sean Christopherson (5):
  KVM: SVM: Drop unused AVIC / kvm_x86_ops declarations
  KVM: x86: Drop @vcpu parameter from kvm_x86_ops.hwapic_isr_update()
  KVM: x86: Check for in-kernel xAPIC when querying APICv for directed
    yield
  KVM: x86: Move "apicv_active" into "struct kvm_lapic"
  KVM: x86: Use lapic_in_kernel() to query in-kernel APIC in APICv
