[PATCH v2 00/13] sched: Clean-ups and asymmetric cpu capacity support

2016-06-22 Thread Morten Rasmussen
Hi, The scheduler is currently not doing much to help performance on systems with asymmetric compute capacities (read ARM big.LITTLE). This series improves the situation with a few tweaks mainly to the task wake-up path that considers compute capacity at wake-up and not just whether a cpu is idle
