numa: ia64: support numa_mem_id() for memoryless nodes
PATCH 200/203 numa: ia64: support numa_mem_id() for memoryless nodes
From: Lee Schermerhorn <[email protected]>
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.
