Subject: [PATCH v2 00/12] sched/fair: Optimize and clean up sched averages

Hi Peter,

This patch series combines the previous cleanup and optimization
series. And as you and Ingo suggested, the increased kernel load
scale is reinstated when on 64BIT and FAIR_GROUP_SCHED. In addition
to that, the changes include Vincent's fix, typos fixes, changelog
and comment reword.

Thanks,
Yuyang
