I don't think the cpuidle folks are really interested in these changes,
but we should Cc them to be polite.

Can you resend patches 9, 10, 11 with a subject like:

  "cpuidle: powernv: Set polling ..."

And Cc the cpuidle folks:

$ ./scripts/get_maintainer.pl -f drivers/cpuidle
rjw at rjwysocki.net
daniel.lezcano at linaro.org
linux-pm at vger.kernel.org
linux-kernel at vger.kernel.org
