The Fn pmap_is_modified and Fn pmap_ts_referenced functions return information about physical pages.


The Fn pmap_is_modified function returns the status of the ``page modified'' bit for the physical page Fa m .

The Fn pmap_ts_referenced function returns a count of reference bits for a page Fa m , clearing those bits. It is not necessary for every reference bit to be cleared, but it is necessary that 0 only be returned when there are no remaining reference bits set on the page.
