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 Acked-by: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/arch/x86_64/mm/numa.c b/arch/x86_64/mm/numa.c index cc02573..b2fac14 100644 --- a/arch/x86_64/mm/numa.c +++ b/arch/x86_64/mm/numa.c @@ -188,11 +188,13 @@ void __init setup_node_zones(int nodeid) memory. */ memmapsize = sizeof(struct page) * (end_pfn-start_pfn); limit = end_pfn << PAGE_SHIFT; +#ifdef CONFIG_FLAT_NODE_MEM_MAP NODE_DATA(nodeid)->node_mem_map = __alloc_bootmem_core(NODE_DATA(nodeid)->bdata, memmapsize, SMP_CACHE_BYTES, round_down(limit - memmapsize, PAGE_SIZE), limit); +#endif size_zones(zones, holes, start_pfn, end_pfn); free_area_init_node(nodeid, NODE_DATA(nodeid), zones,
