Hmm, patches 1..4,6 are in linux-tip and Arnaldo's trees but patch 5 is
in neither.

I suspect Arnaldo was either waiting for an ACK from Ben, or was
expecting Ben to take it?

Sigh.  The port of this patchset to Power6 has not started yet.

It should hardly require a port, it's about five lines. But it doesn't
matter for now.
 

But this patchset does work on Power7 correct ?

Yes, and without it the rest of the series is essentially useless. So I
guess it's better than nothing and we should get it in, we can fix it up
later to work across different chips.

Ben can you grab it, it's all arch/powerpc.
