The reason airlied asked for qemu being upstream first is to avoid
having code in the kernel tree not accepted by qemu yet ...
So, one of the two has to go first ;)
When I did the pull requests patches had passed review on both
qemu-devel (qemu side) and dri-devel (kernel side), so this was really
just a formal "wait for qemu" thing with a very low risk of ABI changes,
and airlied pulled it into drm-next only days after it landed in
qemu/master.
