Subject: [PATCH 3/8] numa: ia64: use generic percpu var numa_node_id() implementation
Date: Thu, 15 Apr 2010 13:30:09 -0400 [thread overview]
Message-ID: <20100415173009.8801.67345.sendpatchset@localhost.localdomain> (raw)

Against: 2.6.34-rc3-mmotm-100405-1609
ia64: Use generic percpu implementation of numa_node_id()
+ intialize per cpu 'numa_node'
+ remove ia64 cpu_to_node() macro; use generic
+ define CONFIG_USE_PERCPU_NUMA_NODE_ID when NUMA configured
