/* Bit position which is always zero in a PTE. We'll use the PAT bit.
* This helps disambiguate PTEs that do not have the Present bit set (MMU_P):
* - If the entire entry is zero, it's an un-mapped virtual page
* - If MMU_PTE_ZERO is set, we flipped this page due to KPTI
* - If PTE_ZERO is set, we flipped this page due to KPTI
* - Otherwise, this was a page-out
