From: Steven Rostedt <rostedt@goodmis.org> When the dax_fault_actor() helper was factored out, it removed the calls to the dax_pmd_insert_mapping event but never removed the event itself. As events created do take up memory (roughly 5K), this is a waste as it is never used. Remove the unused dax_pmd_insert_mapping trace event.
