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. Signed-off-by: Lee Schermerhorn <[email protected]> --- New in V3.
