Please don't supply QEMU patches that update the linux-header files
without specifying which kernel tree and git revision the headers
have come from. In particular, if the headers have not yet hit
upstream kvm-next or mainline then the whole patchset must be marked
as RFC since it can't be committed until the ABI has stabilised.

thanks
