Log Message:
- pmap_remove(): unmap the PTEs *after* we have finished with the
  page tables.
- pmap_enter(): if making a mapping for the same PA rw->ro, write-back
  the cache before doing so.
- pmap_clearbit(): if revoking REF on a page, make sure to wbinv the
  cache if the page has write permission, else inv the cache if the page's
  PTE is valid (XXX we actually wbinv in this case, as well, due to lack
  of idcache_inv_range()).  Only flush the TLB if the PTE changed.
