Subject: [PATCH 5/8] numa: ia64: support numa_mem_id() for memoryless nodes
Date: Thu, 15 Apr 2010 13:30:24 -0400 [thread overview]
Message-ID: <20100415173024.8801.36840.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20100415172950.8801.60358.sendpatchset@localhost.localdomain>
Against: 2.6.34-rc3-mmotm-100405-1609
IA64: Support 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.
