SVN rev 183478 on 2008-09-29 22:13:29Z by kmacy
vm_fault_hold_user_pages will not return if an address in the range passed in
is mapped RO
but an RW mapping exists for the underlying page. This change fixes the bug
by using the
page / NULL returned from pmap_extract_and_hold to determine whether or not
vm_fault needs
to be called.
The bug was pointed out by alc.
