APICv cleanups and a dissertation on handling concurrent APIC access page
faults and APICv inhibit updates.

I've tested this but haven't hammered the AVIC stuff, I'd appreciate it if
someone with the Hyper-V setup can beat on the AVIC toggling.

Sean Christopherson (4):
KVM: x86/mmu: Use vCPU's APICv status when handling APIC_ACCESS

KVM: x86: Move SVM's APICv sanity check to common x86
KVM: x86: Move apicv_active flag from vCPU to in-kernel local APIC
KVM: x86: Use rw_semaphore for APICv lock to allow vCPU parallelism
