The following patch fixes a bug where the guest is still able to access
the apic registers via mmio once the apic has been disabled.
8d860bbeedef kvm: vmx: Basic APIC virtualization controls have three
settings
This causes the x86/apic kvm-unit-test to fail when run on a host
missing this patch.
Without:
FAIL: apic_disable: *0xfee00030: 50014

FAIL: apic_disable: *0xfee00080: f0

This patch has been upstream as of v4.18.
This patch has 3 dependencies which introduce no functional
change, however they add context which allows the patch listed above to
apply cleanly.
c2ba05ccfde2 KVM: X86: introduce invalidate_gpa argument to tlb flush
588716494258 kvm: vmx: Introduce lapic_mode enumeration
a468f2dbf921 kvm: apic: Flush TLB after APIC mode/address change if
VPIDs are in use
