If !CONFIG_HIGHMEM then

enum node_states {
#ifdef CONFIG_HIGHMEM
N_HIGH_MEMORY, /* The node has regular or high memory */
#else
N_HIGH_MEMORY = N_NORMAL_MEMORY,
#endif

So
for_each_online_node(nid) {
pg_data_t *pgdat = NODE_DATA(nid);
free_area_init_node(nid, pgdat, NULL,
find_min_pfn_for_node(nid), NULL);

/* Any memory on that node */
if (pgdat->node_present_pages)
node_set_state(nid, N_HIGH_MEMORY);
^^^ sets N_NORMAL_MEMORY
check_for_regular_memory(pgdat);
