Yeah, that was as Absurd as I am :)

I went to that Absurd idea because we thought we can skip playing with
the sysfs nodes on suspend/hotplug.

And if policy->cpu keeps changing with hotplug, we *may* have to keep
sysfs stuff moving as well. One way to avoid that is by using something
like: policy->sysfs_cpu, but wasn't sure if that's the right path to follow.

Lets see what Saravana's new patchset has for us :)
