Subject[PATCH 0/6] KVM: x86: Apply NX mitigation more precisely
From
This is just the kernel (NX) side of Mingwei's series "Verify dirty
logging works properly with page stats". Relatively to v3 of Mingwei's
series[*], this fixes accounting (and tracking in the nonpaging case)
of disallowed NX huge pages.

I left off the selftests because I disagree with the "Dump stats" change,
and this has snowballed enough.

Mingwei Zhang (1):
KVM: x86/mmu: explicitly check nx_hugepage in
disallowed_hugepage_adjust()

Sean Christopherson (5):
KVM: x86/mmu: Tag disallowed NX huge pages even if they're not tracked
KVM: x86/mmu: Properly account NX huge page workaround for nonpaging
MMUs
KVM: x86/mmu: Set disallowed_nx_huge_page in TDP MMU before setting
SPTE
KVM: x86/mmu: Track the number of TDP MMU pages, but not the actual
pages
KVM: x86/mmu: Add helper to convert SPTE value to its shadow page
