Currently CPUs that have entered nohz idle mode are not being woken up to perform load balancing. Turning on SCHED_MC will fix that, and will also cause CPUs to show up at the correct level of scheduling domain (MC). SCHED_MC would normally also cause SD_SHARE_PACKAGE_RESOURCES to be turned on at the MC level as well, causing a task to be migrated to an idle CPU when the task is woken up. Previous modifications to SD_SHARE_PACKAGE_RESOURCES however have restricted its effect to tasks that have the PF_WAKE_ON_IDLE flag set. Certain target configurations (msm7627a*, msm8660*) are being left out until they are verified with SCHED_MC.
