Now that everything else is unified, NUMA initialization can be unified too. * numa_init_array() and init_cpu_to_node() are moved from numa_64 to numa. * numa_32::initmem_init() is updated to call numa_init_array() and setup_arch() to call init_cpu_to_node() on 32bit too. * x86_cpu_to_node_map is now initialized to NUMA_NO_NODE on 32bit too. This is safe now as numa_init_array() will initialize it early during boot. This makes NUMA mapping fully initialized before setup_per_cpu_areas() on 32bit too and thus makes the first percpu chunk which contains all the static variables and some of dynamic area allocated with NUMA affinity correctly considered.
