Sorry, it's wider because you pushed the last stupid Mike patch. Over my
(obviously too-polite) objections. Most of this is reverting that, just
without actually admitting it.

Not really. As authored, I intended it as a bandaid for systems with small
CPU numbers. Mike made it always on (tho __initdata on large x86 systems),
which IMHO is insane (2MB of initdata?).

Mike: I now think the right long-term answer is Linus' dense cpumap idea + a
convenience allocator for cpumasks. We sweep the kernel for all on-stack
vars and replace them with one or the other. Thoughts?
