Kip Macy e2b2d0e9d5 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.
