While working on a paravirt cpuidle driver for KVM guests, I

These patches should get rid of some artifacts that can break
the logic in the menu governor under certain corner cases, and
make idle state selection work better on CPUs with long C1 exit

I have not seen any adverse effects with them in my (quick)
tests. As expected, they do not seem to do much on systems with
many power states and very low C1 exit latencies and target residencies.

Sorry for the trouble, but can you please resend the series with CCs to linux-pm@xxxxxxxxxxxxxxx? That will make it way easier to handle for me.
