You can use git. I believe gentoo patches are only for config options so if you 
configure it with make oldconfig it *should* be the same as using gentoo-
sources.

cd /usr/src
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-
stable.git
cd linux-stable
git checkout v3.18.9
make oldconfig
make

You can checkout any version committed prior to your last "git pull" 
instantly.
