crap, so much for that theory. I ran latest with those two reverted
overnight, and woke up to a dead box. Over serial console, I see
a bunch of those same compaction oopses (Via sys_mmap_pgoff),
and then kernel BUG at include/linux/mm.h:448! was the last thing
it said before it choked.
I'll redo the bisect. It's possible that one of the 'good' paths just
didn't run for long enough.
