I am slightly confused by the function name mce_notify_irq() and the
boolean meaning. Would it better to rename this function to
mce_notify_user()? As the comment suggests on top, it purpose doesn't
seem to be irq related but to mainly notify the user.

Also, the boolean would probably make more sense then:
	True -> Notified the user
	False -> Did not notify the user
