a critical section as apparently required by both. I don't think either belongs in the event timer front-ends but the callback should handle this as necessary instead just like for example intr_event_handle() does but this is how the other architectures currently handle it, either explicitly or implicitly. - Further rename and reword references to hardclock as this front-end no longer has a notion of actually calling it.
