[PATCH 0/2] KVM: nVMX: Fix VPID + !EPT TLB bugs

[Sean Christopherson]

Fix two bugs reported by Lai where KVM mishandles guest-scoped TLB flushes
when L2 is active.  Bugs confirmed (and confirmed fixed) by the VPID+access
test (patches posted for kvm-unit-tests).

Sean Christopherson (2):
  KVM: nVMX: Flush current VPID (L1 vs. L2) for KVM_REQ_TLB_FLUSH_GUEST
  KVM: nVMX: Emulate guest TLB flush on nested VM-Enter with new vpid12
