@Ray-Ven I don't have the files lying around anymore. I will try to do it again sometime. But until I get to it, you could really do it yourself if you have a little experience with the terminal. I used git as per the instructions on e.g. http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9/. Using git apply you can also apply the patches from http://www.spinics.net/lists/intel-gfx/msg68973.html
