Morten Rasmussen 9e0994c0a1 sched/fair: Avoid pulling tasks from non-overloaded higher capacity groups ... For asymmetric CPU capacity systems it is counter-productive for throughput if low capacity CPUs are pulling tasks from non-overloaded CPUs with higher capacity. The assumption is that higher CPU capacity is preferred over running alone in a group with lower CPU capacity. This patch rejects higher CPU capacity groups with one or less task per CPU as potential busiest group which could otherwise lead to a series of failing load-balancing attempts leading to a force-migration.
