They were generated by the old 'make sync' to remove CONFIG_ 
dependencies.  I guess a better way to generate them is a 'make 
headers-install' from the kernel tree and grab the results.

One of the goals of qemu-kvm.git was to have a standalone repository so 
I could release kvm-kmod and qemu-kvm independently.

Can you detail specific grievances?  Please exclude temporary brokenness

cp from a Linux tree won't compile.  The results of the old 'make sync' 
would do, but a 'make headers-install' is probably better.

Applied, thanks.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
