Mike Rapoport 6b2ad8d763 m68k/mm: make node data and node setup depend on CONFIG_DISCONTIGMEM ... The pg_data_t node structures and their initialization currently depends on !CONFIG_SINGLE_MEMORY_CHUNK. Since they are required only for DISCONTIGMEM make this dependency explicit and replace usage of CONFIG_SINGLE_MEMORY_CHUNK with CONFIG_DISCONTIGMEM where appropriate. The CONFIG_SINGLE_MEMORY_CHUNK was implicitly disabled on the ColdFire MMU variant, although it always presumed a single memory bank. As there is no actual need for DISCONTIGMEM in this case, make sure that ColdFire MMU systems set CONFIG_SINGLE_MEMORY_CHUNK to 'y'.
