Subject[PATCH 0/4] KVM: x86/mmu: Bug fixes and cleanups in get_mmio_spte()
From
Two fixes for bugs that were introduced along with the TDP MMU (though I
strongly suspect only the one reported by Richard, fixed in patch 2/4, is
hittable in practice). Two additional cleanup on top to try and make the
code a bit more readable and shave a few cycles.

Sean Christopherson (4):
KVM: x86/mmu: Use -1 to flag an undefined spte in get_mmio_spte()
KVM: x86/mmu: Get root level from walkers when retrieving MMIO SPTE
KVM: x86/mmu: Use raw level to index into MMIO walks' sptes array
KVM: x86/mmu: Optimize not-present/MMIO SPTE check in get_mmio_spte()
