Subject: [PATCH v2 0/3] Take the scheduling domain into account in numa balancin

This patchset tries to adjust the logic of handling isolate cpus in numa balancing.

patch#1: Clean up for task_numa_migrate().

patch#2: Skips the isolate cpus when gathering numa status and finding
idle cpus in update_numa_stats().

patch#3: Ensure that we do not select an isolated CPU in
task_numa_find_cpu(), even if it is present in the task's CPU mask.

v1 -> v2:
 - collect Prateek's reviewed-by and add the history of
   task_numa_migrate() to commit log.

Chuyi Zhou (3):
  sched/fair: Remove unused task_numa_migrate return value
  sched/fair: Ignore isolated cpus in update_numa_stat
  sched/fair: Ensure select housekeeping cpus in task_numa_find_cpu
