[PATCH 2/4] sched/fair: Introduce arch_sched_asym_prefer_early()

2021-04-05 Thread Ricardo Neri
Introduce arch_sched_asym_prefer_early() so that architectures with SMT can delay the decision to label a candidate busiest group as group_asym_packing. When using asymmetric packing, high priority idle CPUs pull tasks from scheduling groups with low priority CPUs. The decision on using
