Revise vm_pageout_scan()'s handling of partially dirty pages. Specifically,
rather than unconditionally making partially dirty pages fully dirty, only
make partially dirty pages fully dirty if the pmap says that the page has
been modified.
(This change is also a small optimization. It eliminate an unnecessary call
to pmap_is_modified() on pages that are mapped read only.)
