The situation slightly changed. Before the patch in question:
|warning: (PREEMPT && DEBUG_ATOMIC_SLEEP) selects PREEMPT_COUNT which has unmet direct dependencies (COLDFIRE)

so it is just s@...EMPT@...EMPT_COUNT@.

This pops up because DEBUG_ATOMIC_SLEEP can be selected while
kernel/Kconfig.preempt has not been included into Kconfig. This warning
is not limited to m68k but should also pop up on alpha / frv and hexagon.
Those architectures don't include kernel/Kconfig.preempt at all.

Is this something that should be fixed?
