include/asm-generic/topology.h has a fallback:

#ifndef CONFIG_NUMA

/* Other architectures wishing to use this simple topology API should fill
   in the below functions as appropriate in their own <asm/topology.h> 
file. */
#ifndef cpu_to_node
#define cpu_to_node(cpu)        ((void)(cpu),0)
#endif
