Now that the enabled/disabled states for the preemption functions are declared alongside their definitions, the core PREEMPT_DYNAMIC logic is no longer tied to GENERIC_ENTRY, and can safely be selected so long as an architecture provides enabled/disabled states for irqentry_exit_cond_resched(). Make it possible to select HAVE_PREEMPT_DYNAMIC without GENERIC_ENTRY. For existing users of HAVE_PREEMPT_DYNAMIC there should be no functional change as a result of this patch.
