Modified files:
sys/i386/i386 pmap.c
Log:
- Added support for multiple page directory pages to pmap_pinit and
pmap_release.
- Merged pmap_release and pmap_release_free_page. When pmap_release is
called only the page directory page(s) can be left in the pmap pte object,
since all page table pages will have been freed by pmap_remove_pages and
pmap_remove. In addition, there can only be one reference to the pmap and
the page directory is wired, so the page(s) can never be busy. So all there
is to do is clear the magic mappings from the page directory and free the
page(s).
