From 69d81fcde7797342417591ba7affb372b9c86eae Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Sat, 5 Nov 2005 17:25:53 +0100 Subject: [PATCH] x86_64: Speed up numa_node_id by putting it directly into the PDA Not go from the CPU number to an mapping array. Mode number is often used now in fast paths. This also adds a generic numa_node_id to all the topology includes Suggested by Eric Dumazet Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds --- arch/x86_64/mm/srat.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/x86_64/mm/srat.c') diff --git a/arch/x86_64/mm/srat.c b/arch/x86_64/mm/srat.c index 4b2e844..c7aa08a 100644 --- a/arch/x86_64/mm/srat.c +++ b/arch/x86_64/mm/srat.c @@ -203,7 +203,7 @@ int __init acpi_scan_nodes(unsigned long start, unsigned long end) if (cpu_to_node[i] == NUMA_NO_NODE) continue; if (!node_isset(cpu_to_node[i], nodes_parsed)) - cpu_to_node[i] = NUMA_NO_NODE; + numa_set_node(i, NUMA_NO_NODE); } numa_init_array(); return 0; -- cgit v1.1
