Hi all,

The patch set v2 aims to add knowledge about reduced CPU capacity
into the Energy Model (EM) and Energy Aware Scheduler (EAS). Currently the
issue is that SchedUtil CPU frequency and EM frequency are not aligned,
when there is a CPU thermal capping. This causes an estimation error.
This patch set provides the information about allowed CPU capacity
into the EM (thanks to thermal pressure signal). This improves the
energy estimation. More info about this mechanism can be found in the
patches comments.

Changelog:
v2:
- clamp the returned value from effective_cpu_util() and avoid irq
  util scaling issues (Quentin)
v1 is available at [1]

Regards,
Lukasz
