of_node_to_nid and dump_numa_cpu_topology are declared inline in their respective header files, if CONFIG_NUMA is not set. Thus it is only valid to define these functions in numa.c if CONFIG_NUMA is set. (numa.c, despite the name, isn't conditionalized on CONFIG_NUMA, but CONFIG_NEED_MULTIPLE_NODES.)
