Page loaning implies read-only pages, so what issues are there with incompatible cache aliases?
Current page loaning code doesn't consider about virtual cache indexes on new P-V mappings (unless yamt-kmem branch is complete?) and it creates a bunch of possible aliases which might be much more pain than copying pages. --- Izumi Tsutsui
