[PATCH] x86_64: cleanup setup_node_zones called by paging_init v2 setup_node_zones calcuates some variable but only use them when FLAT_NODE_MEM_MAP is set
so change the MACRO postion to avoid calculating. also change it to static Signed-off-by: Yinghai Lu <[EMAIL PROTECTED]> Index: linux-2.6/arch/x86/mm/numa_64.c =================================================================== --- linux-2.6.orig/arch/x86/mm/numa_64.c +++ linux-2.6/arch/x86/mm/numa_64.c @@ -229,8 +229,9 @@ void __init setup_node_bootmem(int nodei node_set_online(nodeid); } +#ifdef CONFIG_FLAT_NODE_MEM_MAP /* Initialize final allocator for a zone */ -void __init setup_node_zones(int nodeid) +static void __init setup_node_zones(int nodeid) { unsigned long start_pfn, end_pfn, memmapsize, limit; @@ -244,14 +245,14 @@ 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 } +#endif void __init numa_init_array(void) { @@ -570,9 +571,11 @@ void __init paging_init(void) sparse_memory_present_with_active_regions(MAX_NUMNODES); sparse_init(); +#ifdef CONFIG_FLAT_NODE_MEM_MAP for_each_online_node(i) { setup_node_zones(i); } +#endif free_area_init_nodes(max_zone_pfns); } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
