Subject: [PATCH 7/8] numa: in-kernel profiling: use cpu_to_mem() for per cpu allocations
Date: Thu, 15 Apr 2010 13:30:36 -0400 [thread overview]
Message-ID: <20100415173036.8801.29768.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20100415172950.8801.60358.sendpatchset@localhost.localdomain>
Against: 2.6.34-rc3-mmotm-100405-1609
Patch: in-kernel profiling -- support memoryless nodes.
In kernel profiling requires that we be able to allocate "local"
memory for each cpu. Use "cpu_to_mem()" instead of "cpu_to_node()"
to support memoryless nodes.
Depends on the "numa_mem_id()" patch.
