Generating the kernel patch:

This is a stripped down description of how I generated the kernel patch.
It is based on how I thought it might have been done by Alpine Linux for
there raspberrypi kernel.

git clone -b rpi-4.5.y https://github.com/raspberrypi/linux.git linux-rpi
cd linux-rpi
git remote add -b linux-4.5.y stable-4.5 \
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
git pull stable-4.5
git diff stable-4.5..rpi-4.5.y > ../linux-4.5.y-rpi-$(date +%Y%m%d).patch
