Log Message:
Change pv_entries to use SLIST.

For VIPT caches, keep track of when pages are dirty so that their content
can be flushed back to main memory.  This is done when the page is
read-only mapped by more than 1 color.  Pages become when either their
modified bit gets set or an unmanaged writeable page is mapped.  When
a page in unmapped or changed to read-only, run pmap_vac_me_harder in
case the page can be mapped read-only.

Thanks are given to Imre Deak for giving me the idea to assert for PVF_DIRTY.
