Not sure I follow. Xen pvops pays attention to whether a particular page is being used as part of a pagetable, and changes its permissions accordingly. But because pagetable pages are strictly kernel-only, we can get away with updating a single kernel-mapping pte which is shared across all processes. In the guest page hinting case, we need to deal with general pages which can be mapped anywhere, so that really does require a full traversal of the pagetables. Presumably rmap would be helpful here.
