From: Lee Schermerhorn <lee.schermerhorn@xxxxxx> Enable 'HAVE_MEMORYLESS_NODES' by default when NUMA configured on ia64. Initialize percpu 'numa_mem' variable when starting secondary cpus. Generic initialization will handle the boot cpu. Nothing uses 'numa_mem_id()' yet. Subsequent patch with modify slab to use this.
