The hard question is how to do this cleanly. Perhaps changing things
slightly so that lib/dump_stack.c provides the 'true' dump_stack() (or
moving it to kernel/dump_stack.c) which calls a notify chain and then
arch_dump_stack() ?

This is a good idea, I'm surprised we didn't already do, so I've just
done it.
