Thanks a lot for this hint! ;-)

Pavel, I've ported the basic i386 CPU hotplug stuff, without the sysfs
interface, to x86-64 (a cut'n'paste kind of work, mostly).  For now, I've
made HOTPLUG_CPU on x86-64 depend on SMP and SOFTWARE_SUSPEND and be set
automatically.

I'm going to test it together with your patch tomorrow.

Greets,
Rafael
