The SD_ASYM_CPUCAPACITY sched_domain flag is supposed to mark the
sched_domain in the hierarchy where all cpu capacities are visible for
any cpu's point of view on asymmetric cpu capacity systems. The
scheduler can then take to take capacity asymmetry into account when
balancing at this level. It a
