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.
----------------------------------------------------------------
