Davidlohr's answer is correct: This is not an "Ubuntu kernel".
3.13.y.z is an "extended stable" kernel which follows the same rules as
the kernel.org official stable kernels. It contains no Ubuntu-specific
patches, and supports the same arch's as mainline.
More details about this and the other Canonical-funded-and-hosted
"extended stable" kernel versions is available here:
