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

Yuyang Du (6):
sched/fair: Generalize the load/util averages resolution definition
sched/fair: Remove SCHED_LOAD_SHIFT and SCHED_LOAD_SCALE
sched/fair: Add introduction to the sched load avg metrics
sched/fair: Remove scale_load_down() for load_avg
sched/fair: Rename scale_load() and scale_load_down()
sched/fair: Remove unconditionally inactive code
