Well, the comment is wrong. The code doesn't actually visit 'gate_vma' if the list of VMA's is empty. Not that the old code did either, so it's not like it's a new bug, but I thought I'd point it out anyway. As if we care (but you can probably trigger this by having an app that does munmap(NULL, TASK_SIZE); which will cause a SIGSEGV on return (because the stack doesn't exist) and then the core-dump should be empty. Not that I tested anythign that evil anyway, nor do I think we really care if it means that the gate_vma doesn't get shown in the core-dump either.
