Subject: [PATCH v4 0/3] sched: account fair load avg consistently

From: Byungchul Park <byungchul.park@....com>

* change from v3 to v4
- optimize - force to use rmb() once when doing migration
- optimize - not add additional variable to task_struct
- change the order of migrate_task_rq() and __set_task_cpu()

* change from v2 to v3
- consider otimization in the case of migration
- split patches to 3 to be reviewed easily

* change from v1 to v2
- make set_task_rq() do that role instead of migration callback
- make set_task_rq() do that role instead of move group callback
- remove the dependancy between last_update_time and check for migration

Byungchul Park (3):
  sched/fair: make it possible to account fair load avg consistently
  sched/fair: split the remove_entity_load_avg() into two functions
  sched: optimize migration by forcing rmb() and updating to be called
    once
