[PATCH v4 4/5] sched: add a new SD_SHARE_POWERDOMAIN for sched_domain

2014-04-11 Thread Vincent Guittot
A new flag SD_SHARE_POWERDOMAIN is created to reflect whether groups of CPUs in a sched_domain level can or not reach different power state. As an example, the flag should be cleared at CPU level if groups of cores can be power gated independently. This information can be used in the load balance d
