SVN rev 213890 on 2010-10-15 05:42:35Z by alc
MFC r209605
Improve bufdone_finish()'s handling of the bogus page. Specifically, if
one or more mappings to the bogus page must be replaced, call pmap_qenter()
just once. Previously, pmap_qenter() was called for each mapping to the
bogus page.
MFC r209902
Change the implementation of vm_hold_free_pages() so that it performs at
most one call to pmap_qremove(), and thus one TLB shootdown, instead of one
call and TLB shootdown per page.
Simplify the interface to vm_hold_free_pages().
