If any of the numa topology functions--numa_node_id() et al--have not been overridden by the arch, we can define them as static inline functions. Note that this means that cpu_to_node() can no longer be used as an lvalue. However, the tree contains no such usage currently, and a subsequent patch will add a function to set the 'numa_node' for a specified cpu. x86 defines numa_node_id() as a static inline function when CONFIG_NUMA is not set. Add #define of numa_node_id to itself to indicate this override of the default definition, so we can build !NUMA with this patch applied. Maybe we should move the default definitions to asm-generic/topology.h? Or remove it altogether? x86_64 !NUMA seems to build without it.
