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 r...@rjwysocki.net daniel.lezc...@linaro.org linux...@vger.kernel.org linux-ker...@vger.kernel.org cheers
