[PATCH] x86_64: sparsemem does not need node_mem_map
Seems we are trying to init the node_mem_map when we don't need to, for example when SPARSEMEM is enabled. This causes the error below during compilation. Use CONFIG_FLAT_NODE_MEM_MAP to gate allocation and init. arch/x86_64/mm/numa.c: In function `setup_node_zones': arch/x86_64/mm/numa.c:191: error: structure has no member named `node_mem_map' Signed-off-by: Andy Whitcroft <apw@shadowen.org> Acked-by: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
