Is this repo deprecated?

It looks like the DockerHub images are pulling from https://github.com/linuxkit/linuxkit/blob/master/kernel/Dockerfile which in turn points to https://www.kernel.org/pub/linux/kernel/${KERNEL_MAJOR}/linux-${KERNEL_VERSION}.tar.xz.

Is this repo used anymore?

We use this to generate the patches that we add to the patch directories, rather than cloning this repo directly. So yes it is used, but you should not in general use this repo, as it does not necessarily have all the kernel patch releases in it.
