PG_REFERENCED changes in vm_pageout_object_deactivate_pages(). Simplify this function's inner loop using TAILQ_FOREACH(), and shorten some of its overly long lines. Update a stale comment. Assert that PG_REFERENCED may be cleared only if the object containing the page is locked. Add a comment documenting this. Assert that a caller to vm_page_requeue() holds the page queues lock, and assert that the page is on a page queue. Push down the page queues lock into pmap_ts_referenced() and pmap_page_exists_quick(). (As of now, there are no longer any pmap functions that expect to be called with the page queues lock held.) Neither pmap_ts_referenced() nor pmap_page_exists_quick() should ever be passed an unmanaged page. Assert this rather than returning "0" and "FALSE" respectively. ARM: Simplify pmap_page_exists_quick() by switching to TAILQ_FOREACH(). Push down the page queues lock inside of pmap_clearbit(), simplifying pmap_clear_modify(), pmap_clear_reference(), and pmap_remove_write(). Additionally, this allows for avoiding the acquisition of the page queues lock in some cases. PowerPC/AIM: moea*_page_exits_quick() and moea*_page_wired_mappings() will never be called before pmap initialization is complete. Therefore, the check for moea_initialized can be eliminated. Push down the page queues lock inside of moea*_clear_bit(), simplifying moea*_clear_modify() and moea*_clear_reference(). The last parameter to moea*_clear_bit() is never used. Eliminate it. PowerPC/BookE: Simplify mmu_booke_page_exists_quick()'s control flow. Reviewed by: kib@ |
