The patch titled
Subject: m68k/mm: make node data and node setup depend on CONFIG_DISCONTIGMEM
has been removed from the -mm tree. Its filename was
m68k-mm-make-node-data-and-node-setup-depend-on-config_discontigmem.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: 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'.
