3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Charles Wang <muming...@taobao.com> commit 749c8814f08f12baa4a9c2812a7c6ede7d69507d upstream. Azat Khuzhin reported high loadavg in Linux v3.6 After checking the upstream scheduler code, I found Peter's commit: 5167e8d5417b sched/nohz: Rewrite and fix load-avg computation -- again not fully applied, missing the call to calc_load_exit_idle(). After that idle exit in sampling window will always be calculated to non-idle, and the load will be higher than normal. This patch adds the missing call to calc_load_exit_idle().
