When I was tracking th MACHINE_NEW_NONCONTIG bug on sun3x,
it seemed that "using pages reserved for PROM" bug in
sun3x/pmap.c caused problem like "everything core dumps" bug.
Then I suspect that MNN changes (both sun3 and sun3x) fixed the bug,
but I'm not sure. At least, I have never seen "everything core dumps"
on my 3/80 running UVM kernels.
