Subject: [PATCH/RFC 5/6] numa: ia64: support numa_mem_id() for memoryless nodes
Date: Fri, 13 Nov 2009 16:18:17 -0500 [thread overview]
Message-ID: <20091113211817.15074.72532.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20091113211714.15074.29078.sendpatchset@localhost.localdomain>
PATCH/RFC numa: ia64: support memoryless nodes
Against: 2.6.32-rc5-mmotm-091101-1001
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.
