Hi Grant,

of_node_to_nid() is only relevant for NUMA.  Don't force architectures to
implement it if CONFIG_NUMA is not set.

Why not just do:

#ifndef of_node_to_nid
static inline int of_node_to_nid(struct device_node *device) { return 0; }
#define of_node_to_nid	of_node_to_nid
#endif

in include/linux/of.h

and then add:

#define of_node_to_nid	of_node_to_nid

Where it is declared/defined for each arch ...
(it would be nice if all the archs were consistent in where it was
declared).
