This is a collection of rather loosely coupled small changes to the cfs scheduler related to:
Comments (patch 1/7, 2/7): Remove/fix some outdated comments related to 'power aware scheduling' and smpnice. Load-balance (patch 3/7 - 5/7): Change unit of load_above_capacity in calculate_imbalance() from [load] to [load/capacity] Refactoring logic in fix_small_imbalance() and remove cpu_avg_load_per_task(). Misc (patch 6/7, 7/7): Reorder update_sd_lb_stats() and use group_cfs_rq(se) throughout fair.c.
