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 --- include/asm-x86_64/numa.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/asm-x86_64/numa.h') diff --git a/include/asm-x86_64/numa.h b/include/asm-x86_64/numa.h index bcf55c3f7f7f..d51e56fdc3da 100644 --- a/include/asm-x86_64/numa.h +++ b/include/asm-x86_64/numa.h @@ -17,6 +17,8 @@ extern void numa_add_cpu(int cpu); extern void numa_init_array(void); extern int numa_off; +extern void numa_set_node(int cpu, int node); + extern unsigned char apicid_to_node[256]; #define NUMA_NO_NODE 0xff -- cgit v1.2.3
