sched: remove fixed NR_CPUS sized arrays in kernel_sched_c
* Change fixed size arrays to per_cpu variables or dynamically allocated
arrays in sched_init() and sched_init_smp().
(1) static struct sched_entity *init_sched_entity_p[NR_CPUS];
(1) static struct cfs_rq *init_cfs_rq_p[NR_CPUS];
(1) static struct sched_rt_entity *init_sched_rt_entity_p[NR_CPUS];
(1) static struct rt_rq *init_rt_rq_p[NR_CPUS];
static struct sched_group **sched_group_nodes_bycpu[NR_CPUS];
(1) - these arrays are allocated via alloc_bootmem_low()
* Change sched_domain_debug_one() to use cpulist_scnprintf instead of
cpumask_scnprintf. This reduces the output buffer required and improves
readability when large NR_CPU count machines arrive.
* In sched_create_group() we allocate new arrays based on nr_cpu_ids.
