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

[Yuyang Du <yuyang.du@intel.com>]

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
