From: Raphael Gault <raphael.gault@xxxxxxx> Both __guest_entry and __guest_exit functions do not setup a correct stack frame. Because they can be considered as callable functions, even if they are particular cases, we chose to silence the warnings given by objtool by annotating them as non-standard.
