Wow, thanks.

But FYI I would have been happy with allocating them for each possible CPU,
rather than doing the hotplug callback thing.

If you really *can* have 4096 CPUS, I'm not so upset about spending 2M; it's
when you've got 2 CPUs and the distro has set CONFIG_NR_CPUS=4096 that I
care about.

I'm not saying to fix it, I'm just saying you went beyond the call of duty.

Kudos,
Rusty.
