It does not help after these 4 patches applied.

Gregory Haskins (4):
     sched: make task_hot() once again use sd->cache_hot_time
     Revert "sched: zap the migration init / cache-hot balancing code"
     Revert "[PATCH] sched: remove cache_hot_time"
     revert "sched: sched_cacheflush is now unused"
