I'm running Ubuntu 15.10 on a new laptop but in order to get proper full support for this hardware I apparently need the 4.4 kernel + a custom patch. See here if you're interested in the details.
I know about the mainline kernel PPAs but my understanding is that they don't come with source. If this is the case, This would seem to eliminate the possibility of using a mainline kernel PPA because I can't patch it. So I've been trying to check out the git source and build it but can't find up to date, relevant instructions.
Can somebody help with instructions for building a 4.4 kernel on 15.10?
