I've just downloaded 2017-03-02-raspbian-jessie.img. It's running kernel 4.4.50+. Where can I get the source for this kernel as built in the distribution?
The rpi-4.4.y branch of https://github.com/raspberrypi/linux doesn't include it - the HEAD of that branch is apparently still 4.4.48.
Is this tagged, or archived, or something, somewhere?
