powerc tree maintainership status

[Benjamin Herrenschmidt]

Hi Folks !

I'm going to be getting some surgery next week. In the good case, I
should be officially back to work 2 weeks later, but I might end
up being unavailable for longer.

So while I'm away, Michael Ellerman and Paul Mackerras are going to take
care of the powerpc tree. I'll make sure Paul and I sign Michael's PGP
key before I leave.

Cheers,
Ben.
