[PATCH 0/4] consolidate and cleanup CPU capacity

[Vincent Guittot]

This is the 1st part of consolidating how the max compute capacity is
used in the scheduler and how we calculate the frequency for a level of
utilization.

Fix some unconsistancy when computing frequency for an utilization. There
can be a mismatch between energy model and schedutil.

Next step will be to make a difference between the original
max compute capacity of a CPU and what is currently available when
there is a capping applying forever (i.e. seconds or more).

Vincent Guittot (4):
  sched: consolidate and cleanup access to CPU's max compute capacity
  topology: add a new arch_scale_freq_reference
  cpufreq/schedutil: use a fixed reference frequency
  energy_model: use a fixed reference frequency
