Pallipadi, Venkatesh 816bb611e4 cpuidle: Add decaying history logic to menu idle predictor ... Add decaying history of predicted idle time, instead of using the last early wakeup. This logic helps menu governor do better job of predicting idle time. With this change, we also measured noticable (~8%) power savings on a DP server system with CPUs supporting deep C states, when system was lightly loaded. There was no change to power or perf on other load conditions.
