Well... if a new problem is also remedied by use if IBRS/IBPB and retpoline, I think we can happily call it a subclass of "Spectre v2". And if it *isn't* addressed by those same things, then it's clearly something different. Either way, these messages should be 'v2', no? On the whole though, there are plenty of better things to be worrying about :)
