Enable ENERGY_MODEL to make that happen. This will increase energy efficiency of the big.LITTLE platform by smart decisions in scheduling tasks in non-heavy workloads. Add SCHED_MC in order to create another level in scheduling domains: 'MC'. This improves scheduler's decisions on platforms with CPU clusters, such as big.LITTLE.
