--- 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().
