KVM: MMU: Set nx bit correctly on shadow ptes While the page table walker correctly generates a guest page fault if a guest tries to execute a non-executable page, the shadow code does not mark it non-executable. This means that if a guest accesses an nx page first with a read access, then subsequent code fetch accesses will succeed. Fix by setting the nx bit on shadow ptes.
