basically it appears that your machine, when the kernel asks for C2,
exits C2 immediately again.

The old algorithm somehow caught this and stopped asking for C2 most of
the time; the new algorithm doesn't see any activity and asks for C2
again.

What the patch does is tell the kernel to just not use C2 at all...
