You might want to reconsider that.  4.1.2 is too new, it is not nearly as
safe as you might think to use that kernel.

Actually, if the patch you need already went to stable@lists.kernel.org, it
will land in 3.16-ckt (the longterm branch that is "upstream" of the Debian
jessie kernel), and maybe even in a Debian kernel update, well before I'd
consider 4.1.y safe to use.

So, IMHO, it would be safer for you to get the Debian kernel sources, and
attempt to add the relevant patch, "cherry picked" from 4.1.2 (or if you
wait for it, from 3.16-ckt).

This is the "upstream" tree for 3.16 longterm (aka 3.16-ckt), it is
maintained by the Canonical Kernel Team:
http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y

Note that the Debian kernel has a lot more patches on top of 3.16-ckt.

This is the Debian jessie kernel tree (development), maintained by the
Debian kernel team:
http://anonscm.debian.org/viewvc/kernel/dists/jessie/linux/

You will need to read this to build a development snapshot of the Debian
jessie kernel:
