Subject: numa: ia64: support numa_mem_id() for memoryless nodes
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.
