From fd1197f1131a1f1d8bc192f9cfbbe17e305f17f3 Mon Sep 17 00:00:00 2001 From: Lee Schermerhorn Date: Wed, 26 May 2010 14:45:01 -0700 Subject: [PATCH] numa: ia64: support numa_mem_id() for memoryless nodes 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.
