SVN rev 215525 on 2010-11-19 15:12:19Z by cperciva
Make pmap_release consistent with pmap_pinit with respect to unpinning
pages. The pinning of NPGPTD pages is #if 0ed out in pmap_pinit (I'm
not quite sure why...) and this commit adds a corresponding #if 0 in
pmap_release to avoid unpinning those pages.
Some versions of Xen seem to silently ignore requests to unpin pages
which were never pinned in the first place, but some return an error
(causing FreeBSD to panic) prior to this commit.
