That commit was added in 4.5-rc1 and it was not cc'd to stable. We should request this commit in Xenial on the kernel team mailing list. Do you want to do that David, or do you want me to?

When booting 4.3 kernels, the touchpad is works. Expected: When I move a finger touching the touchpad, an arrow should move accordingly on the screen. What happens instead: nothing. I've tried an upstream 4.4 kernel; problem is present there as well. I've booted with pci=noaer due to another bug that would otherwise spam dmesg. Removing it does not fix the problem.
