RETURN VALUES
The pmap_is_modified function returns the status of the ""page modified"" bit for the physical page m. The pmap_ts_referenced function returns a count of reference bits for a page 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.
