Yep, I understand. When I was patching in rmap12f I had to manually
merge the little bit into mm/bootmem.c and the offset was several hundred
lines. Then I realized just how much WLI's bootmem patch changes.

Actually, I'm going to recompile -mjc2 without lock breaking to see if that
helps. Then try without prempt altogether. If either of those two fix the

and your latest patch and merge myself. Heh, I want to keep testing -mjc.
There are so many nice things in there. ;)
