Azat Khuzhin reported high loadavg in Linux v3.6
After checking the upstream scheduler code, I found Peter's commit:
5167e8d541 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().
