So I suspect that switching the order between tracehook_notify_resume() (which ends up calling task_work_run()) and do_signal() done by an earlier patch in this series intends to ensure the information about the instruction pointer causing the #MC is not overwritten by do_signal() (but I'm just guessing). If it's the case, I think it should be clearly stated as the intent of the earlier patch. Thanks, Mathieu -- Mathieu Desnoyers EfficiOS Inc. http://www.efficios.com
