Well, as 0/5 explains, this whole patchset is a suspend/resume-only fix.
So we need special-case handling for suspend/resume in cpusets. So the
additional code is justified, IMHO. It prepares the ground for patch 5.

Again, I split it up here because I didn't want to clutter patch 5; it is
complex enough as it is... ;-)
