https://bugzilla.kernel.org/show_bug.cgi?id=206795 thomas.lendacky@xxxxxxx changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |thomas.lendacky@xxxxxxx --- Comment #1 from thomas.lendacky@xxxxxxx --- Looks like the backport to the stable tree wasn't correct and I didn't notice it when it came through my inbox. The change from the upstream form: kvm_mmu_set_mmio_spte_mask(mask, mask, PT_WRITABLE_MASK | PT_USER_MASK); to the 4.19 (and 4.14) tree should be: kvm_mmu_set_mmio_spte_mask(mask, mask); Instead it was: kvm_mmu_set_mmio_spte_mask(mask, PT_WRITABLE_MASK | PT_USER_MASK); which triggers the BUG_ON(). -- You are receiving this mail because: You are watching the assignee of the bug.
