In that case we are missing one definition __inc_zone_state. Provide that missing __inc_zone_state. (akpm: NUMA && !SMP sounds odd, but I am told "But there is the concept of cpuless nodes. A NUMA system without SMP has a single processor but multiple memory nodes. This used to work before on IA64 (wasn't aware of it, never seen anyone with this kind of thing).")
