Quite frankly, I'm not convinced.

Yeah, yeah, most distro's end up always enabling CPU hotplug due to 
suspend/resume, but:

 - desktop PC's aren't where most memory pressures are anyway

 - on UP, CONFIG_HOTPLUG_CPU isn't on even if you do have suspend/resume

 - we should still care about embedded devices, and while some of them are 
   growing up (and having SMP and not caring about a few tens of kB of 
   memory), I don't think that's a valid argument for the other ones.

So. I'd rather we try to keep our init sections, and continue to spend 
effort on fixing them. If at all possible.
