The right approach to linux-headers changes is to split the patch into 2 
separate patches. One patch with the linux-headers update. Another patch with 
the actual functional change.

That way I can delay the inclusion into QEMU until the API changing patch makes 
Avi's tree. Until that point, the API isn't considered stable, so ioctl and CAP 
numbers could still change. When it's in, I'd usually redo the linux-headers 
patch and apply your functional patch on top.

That way we ensure that we're always in a consistent state with linux-headers.
