Log Message:
Pass accurate protection info from ubc_uiomove() to the pager.
Fixes nfs{,ro}_fileio tests on at least sparc64 (and probably macppc
and other fat endian machines).
The problem was that nfs was fooled to thinking read() caused a
write fault because of VM_PROT_WRITE being unconditionally set and
therefore set NMODIFIED on a r/o file system. It is absolutely
beyond me why the test worked on i386/amd64. Incidentally, I seem
to have "misplaced" a few goats.
