Come on. The thing is, I'm not debating the existence of computers that don't have x86_64-v2, but I *am* debating the usefulness of making QEMU run on them and any extra information can be interesting. > Can you tell me why you never commented on buffer_is_zero improvements, where > v1 was sent in October?

If there's anything that you think I can help reviewing, feel free to let me know offlist. Paolo
