pmap_copy_page() will never have any mappings. Therefore, it is unnecessary to do a cache clean for that page. Add assertions in #ifdef DEBUG that assert this invariant. This shaves some cycles off the frequently-called pmap_zero_page() and pmap_copy_page() (no need to look up the dst page's vm_page structure, and one less function call to clean the page). |
