Subject: [PATCH v2 0/6] sched/fair: Clean up sched metric definitions

Hi Peter and Ingo,

As discussed recently, the sched metrics need a little bit cleanup. This
series of patches attempt to do that: refactor, rename, remove...

Thanks a lot to Ben, Morten, Dietmar, Vincent, and others who provided
valuable comments.

v2 changes:
- Rename SCHED_RESOLUTION_SHIFT to SCHED_FIXEDPOINT_SHIFT, thanks to Peter
- Fix bugs in calculate_imbalance(), thanks to Vincent
- Fix "#if 0" for increased kernel load

Thanks,
Yuyang
