Subject: [PATCH 0/7] KVM: a bunch of fixes
Date: Mon,  2 Nov 2026 18:14:21 -0500	[thread overview]
Message-ID: <20261102231428.13523-1-pbonzini@redhat.com> (raw)

Seven fixes ranging from performance issues to missing checks and potential
use of a stale role.  All except the last one are Cc'd to stable, and all
of them are already on their way to Linus.

  KVM: nSVM: Check validity of vmcs01 save area copied from SMRAM on RSM
  KVM: x86/mmu: Conditionally resched when retrying gPTE walk on A/D
    update failure
  KVM: x86: Conditionally resched when restarting REP string emulation
  KVM: nVMX: Process each host MSR entry at most once when unwinding
    failed VM-Entry
  KVM: x86/mmu: Cap number of parent PTEs per SP at 1000 (the arbitrary
    rmap limit)
  KVM: x86: Unconditionally reset MMU context when emulating INIT
  KVM: x86: Flush guest TLB when emulating a RESET to strictly honor the
    spec
