    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?

    Rusty.
