sched: entity load-tracking load_avg_ratio
This patch adds load_avg_ratio to each task. The load_avg_ratio is a variant of load_avg_contrib which is not scaled by the task priority. It is calculated like this: runnable_avg_sum * NICE_0_LOAD / (runnable_avg_period + 1). Signed-off-by: Morten Rasmussen <Morten.Rasmussen@arm.com>
