Hi Vijay,

It's getting much closer, just a few comments in each patch. As Gleb
points out, please try to use git send-mail (or even stg mail) so that
threading is maintained for these. A side effect will be that you can't
send kernel & qemu patches in the same series, but that's not
necessarily a bad thing. Thanks,

Alex
