We backport selftests back to stable trees. People run selftests on
stable kernels as well, so it's both important to make sure that a
backport didn't brake anything, and to locate possible missing stable
patches.
It is also the case that backporting selftests can't "break" the kernel.
They are disconnected from the kernel's build process so we can be less
conservative about backporting them.
