Make the double fault handler use CPU-specific stacks. Add some
abstraction to simplify future change of other exception handlers to go

Add a new notification of the event through the die notifier chain,
also providing some environmental adjustments so that various
infrastructural things work independent of the fact that the fault and
the callbacks are running on other then the normal kernel stack.

This patch doesn't apply for me to the extent that I'm hesitant to fix
it up manually. Could you please refresh it against current -linus?
P.S. All your patches came through QP-damaged, which made them more
difficult to deal with manually.
