Subject: [PATCH 0/2] sched/fair: feec()/scale_rt_capacity() improvements

This patch-set aims to improve:
 - find_energy_efficient_cpu() by removing max_spare_cap_cpu from
   the candidate CPUs if prev_cpu is already the CPU with the
   maximum spared capacity.
 - scale_rt_capacity() by using irq scaling on RT and DL rq signals
   and removing irq signal from the available remaining capacity.

Pierre Gondois (2):
  sched/fair: Check if prev_cpu has highest spare cap in feec()
  sched/fair: Use IRQ scaling for all sched classes
