Backporting it from Kernel 4.1 is quite simple. Just two patches
have trivial conflicts.

I did a quick backport at:
	https://git.linuxtv.org/mchehab/experimental.git/log/?h=3Dv3.18.102%2bCVE

Please notice that I didn't test it yet.

Will build such Kernel and see how it behaves with compat32.

If it works fine, I'll submit for stable.
