CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same functionality which today depends on CONFIG_PREEMPT. Switch the Kconfig dependency, entry code and preemption handling over to use CONFIG_PREEMPTION. Add PREEMPT_RT output in show_stack().
