There are two cases we need to adjust page size in set_spte:
1): the one is other vcpu creates new sp in the window between mapping_level()
and acquiring mmu-lock.
2): the another case is the new sp is created by itself (page-fault path) when
guest uses the target gfn as its page table.
There are two cases we need to adjust page size in set_spte:
1): the one is other vcpu creates new sp in the window between mapping_level()
and acquiring mmu-lock.
2): the another case is the new sp is created by itself (page-fault path) when
guest uses the target gfn as its page table.
