Hi Michael, Ben, Paul,

Do you know if anyone has tried this series on PowerPC?

I have. No obvious breakage.

My test does a loop of adding and removing multiple CPUs multiple times,
and in the past that has uncovered refcounting bugs. So I don't think
we're leaking any with this series applied.

I used the tracepoint patch to keep an eye on the refcounts :)

I'm happy for this series to go into linux-next where it should get some
more testing.

cheers
