Corrado Zoccolo 672917dcc7 cpuidle: menu governor: reduce latency on exit ... Move the state residency accounting and statistics computation off the hot exit path. On exit, the need to recompute statistics is recorded, and new statistics will be computed when menu_select is called again. The expected effect is to reduce processor wakeup latency from sleep (C-states). We are speaking of few hundreds of cycles reduction out of a several microseconds latency (determined by the hardware transition), so it is difficult to measure.
