max_mapnr is essentially the size of the memory map for systems that use FLATMEM. There is no reason to calculate it in each and every architecture when it's anyway calculated in alloc_node_mem_map(). Drop setting of max_mapnr from architecture code and set it once in alloc_node_mem_map(). While on it, move definition of mem_map and max_mapnr to mm/mm_init.c so there won't be two copies for MMU and !MMU variants.
