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.

sched/fair: Rename variable names for sched averages
sched/fair: Change the variable to hold the number of periods to
32bit integer
sched/fair: Add __always_inline compiler attribute to

documentation: Add scheduler/sched-avg.txt
sched/fair: Generalize the load/util averages resolution definition
