Two small cleanups in what is effectively common MMU code. The following changes since commit 41bccc98fb7931d63d03f326a746ac4d429c1dd3: Linux 6.8-rc2 (2024-01-28 17:01:12 -0800) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-generic-6.9 for you to fetch changes up to ea3689d9df50c283cb5d647a74aa45e2cc3f8064: KVM: fix kvm_mmu_memory_cache allocation warning (2024-02-22 17:02:26 -0800) ---------------------------------------------------------------- KVM common MMU changes for 6.9: - Harden KVM against underflowing the active mmu_notifier invalidation count, so that "bad" invalidations (usually due to bugs elsehwere in the kernel) are detected earlier and are less likely to hang the kernel. - Fix a benign bug in __kvm_mmu_topup_memory_cache() where the object size and number of objects parameters to kvmalloc_array() were swapped. ---------------------------------------------------------------- Arnd Bergmann (1): KVM: fix kvm_mmu_memory_cache allocation warning Sean Christopherson (1): KVM: Harden against unpaired kvm_mmu_notifier_invalidate_range_end() calls virt/kvm/kvm_main.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-)
