We can't release any qemu that depends on something not upstream.

This far from a qemu release, we can consider anything in in kvm.git
master (or slightly trailing that, kvm.git linux-next) as upstream. 
It's very rare that an ABI gets pulled out of that and not merged, and
if it is, we can pull out the qemu feature.  An ABI can change, but that
just means we need to echo the change in qemu.

As qemu gets closer to release, we'll need to look at Linus' tree
instead of kvm.git.

Of course I can complain about my patches later.

But yes, if your change involves multiple subsystem, get it through the
most affected subsystem and get acks from the rest.
