This issue (checkstop) only occurred a once or twice on a P9 Mihawk
with 1TB of RAM and 1TB of swap. It's hard to reproduce. It seems
we have a fix but I misunderstood some parts of the kernel page
allocation scheme and, so, I am not entirely the root issue is
well analyzed. This patch can wait until I grab a larger system
with 2TB.
I will send a v2. Greg had some valuable comments on extra
cleanups.
Thanks,
C.
