45 On fast page fault path, we will use cmpxchg to atomically set the spte W
46 bit if spte.SPTE_HOST_WRITEABLE = 1 and spte.SPTE_WRITE_PROTECT = 1, or

213 parent_ptes bit 0 is zero, only one spte points at this page and
214 parent_ptes points at this single spte, otherwise, there exists multiple
231 Only present on 32-bit hosts, where a 64-bit spte cannot be written
295 - check for valid generation number in the spte (see "Fast invalidation of
308 - walk the shadow page table to find the spte for the translation,
310 - If this is an mmio request, cache the mmio info to the spte and set some
311 reserved bit on the spte (see callers of kvm_mmu_set_mmio_spte_mask)
