GFxxx/GM1xx support the selection of 64/128KiB big pages globally. GM2xx supports the same, as well as another mode where the page size can be selected per-instance. We default to 128KiB pages (With per-instance for GM200, but the current code selects 128KiB there already) as the MMU code isn't currently able to handle otherwise.
