Log:
SVN rev 191986 on 2009-05-11 05:16:57Z by alc
Revert CVS revision 1.94 (svn r16840). Current pmap implementations don't
suffer from the race condition that motivated revision 1.94. Consequently,
the work-around that was implemented by revision 1.94 is no longer needed.
Moreover, reverting this work-around eliminates the need for
vfs_busy_pages() to acquire the page queues lock when preparing a buffer
for read.
