Before the patch in question: |warning: (PREEMPT && DEBUG_ATOMIC_SLEEP) selects PREEMPT_COUNT which has unmet direct dependencies (COLDFIRE) so it is just s@PREEMPT@PREEMPT_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?
