Subject: [PATCH 5.10/5.11 0/9] Fix missing TLB flushes in TDP MMU
Date: Sat, 10 Apr 2021 11:12:20 -0400	[thread overview]
Message-ID: <20210410151229.4062930-1-pbonzini@redhat.com> (raw)

The new MMU for two-dimensional paging had some missing TLB flushes
in 5.10 and 5.11.  This series backports some generic improvements
to simplify the backport in the last four patches.

Ben Gardon (5):
  KVM: x86/mmu: change TDP MMU yield function returns to match
    cond_resched
  KVM: x86/mmu: Merge flush and non-flush tdp_mmu_iter_cond_resched
  KVM: x86/mmu: Rename goal_gfn to next_last_level_gfn
  KVM: x86/mmu: Ensure forward progress when yielding in TDP MMU iter
  KVM: x86/mmu: Yield in TDU MMU iter even if no SPTES changed

Paolo Bonzini (1):
  KVM: x86/mmu: preserve pending TLB flush across calls to
    kvm_tdp_mmu_zap_sp

Sean Christopherson (3):
  KVM: x86/mmu: Ensure TLBs are flushed when yielding during GFN range
    zap
  KVM: x86/mmu: Ensure TLBs are flushed for TDP MMU during NX zapping
  KVM: x86/mmu: Don't allow TDP MMU to yield when recovering NX pages
