KVM: MMU: only write protect mappings at pagetable level If a pagetable contains a writeable large spte, all of its sptes will be write protected, including non-leaf ones, leading to endless pagefaults. Do not write protect pages above PT_PAGE_TABLE_LEVEL, as the spte fault paths assume non-leaf sptes are writable.
