sched_init_domainsSet up scheduler domains and groups. For now this just excludes isolated* CPUs, but could be used to exclude other special cases in the future.
partition_sched_domains_lockedPartition sched domains as specified by the 'ndoms_new'* cpumasks in the array doms_new[] of cpumasks. This compares* doms_new[] to the current sched domain partitioning, doms_cur[].* It destroys each deleted domain and builds each new domain.
