The bulk of this series is comprised of the selftest portion of the vDSO cleanup[*]. The big difference from the full vDSO series is to reuse as much of the existing selftest code as possible. There is still a bit of homebrew code in defining the low level assertion macro, but much less so than in the previous from-scratch version. Cc'd Andy, who also happens to be a reviewer for the harness code, on the off chance he has bandwidth to weigh in. Tagged for_v2? to make it clear that this doesn't need to be rushed into v23.
