Cool, thanks for doing that. I think a lot of this came from Nick Piggin
a long time ago, but I was bad about attributing it.

I wonder how good the coverage is - I don't think it's been seriously
updated since 2010 and presumably it isn't hitting on later-added
features. Doesn't matter - someone will add things later if needed.
And when I bug them to update the test harness ;)

I don't think it will link on my system - I have no liburcu by default.
I wonder if this will break lots of people's "make kselftest".

I'll get all this into -next tomorrow. Hopefully Ross will have time
to go through it sometime (non-urgently - it's 4.6 stuff).
