73 - Host-writable means the gfn is writable in the host kernel page tables and in
75 - MMU-writable means the gfn is writable in the guest's mmu and it is not
135 - The pfn is writable and therefore it cannot be shared between different gfns
147 writable between reading spte and updating spte. Like below case:
194 If the spte is updated from writable to readonly, we should flush all TLBs,
196 writable spte might be cached on a CPU's TLB.
198 As mentioned before, the spte can be updated to writable out of mmu-lock on
