Worth nothing here that linux-headers patches should be generated using 
scripts/update-linux-headers.sh.

Since this linux-headers update includes changes that aren't merged into the 
kernel yet, I would still use update-linux-headers.sh -- but also include in 
the commit message that this is a placeholder patch that includes unmerged uapi 
changes.  Then once the kernel changes merge you can just have a proper 
linux-headers update patch in a subsequent qemu series.
