Why? The way this is being submitted I don't see why we should treat Jan's patch any different from a patch by IBM or Samsung where we've asked folks to fix the license to comply with what I thought was our new policy (it does not even contain a from-x-on-GPLv2+ notice). If we want to get rid of qemu-kvm by pulling this in nontheless (for which I do have sympathies from a packaging perspective) why not instead do a git-merge from qemu-kvm so that we have the full file history at hands inside qemu.git?
