Looks ok, but I note that I don't seem to find an email talking about
the maintainership change.

In general, I really prefer seeing hand-off. I guess in this case
there wasn't all that much hand-off to be done, but I think the last
few changes came from pulling from Guenter..

Hi Linus,

sorry for not keeping you in the loop. No bad intentions, I just know that
you are busy. I knew about this change, and I had offered to send the pull
request. Stafford wanted to do it himself, so I figured I'd only (need to)
get involved if needed.

I had a look through the changes, ran a diff against mainline, and tested the
resulting code in qemu. I did this both with the previous version and with the
version rebased to v4.9. I even checked that Stafford now has his key signed.
It all looks ok to me. Please consider this a Tested-by: and Reviewed-by:
from me for the entire series.

Now all we have left to do is to ask Stafford not to rebase to the latest
kernel before sending his pull requests...

Thanks,
Guenter

Thanks Guenter, 

I see Linus did do the merge already, but just for completion here is a
bit more about the maintainer handoff. I sent this in some of my earlier
pull requests, I should have included it to Linus.

Mail threads from Jonas (previous maintainer)
https://lkml.org/lkml/2015/5/13/469 - mail from Jonas mentioning
                                      he is no longer able to maintain
https://lkml.org/lkml/2015/6/11/426 - mail from Jonas mentioning stefan
                                      is to be the new maintainer

Ideally Stefan Kristiansson would have become the maintainer but he
does not seem to have much time recently.  I am in talks with Stefan
regularly via the #openrisc freenode irc room.  Also, Stefan and I have
met last summer and did a pgp key signing.

Either way, all is set now.  I'll be working on the next batch of
patches now.

Thank you,

-Stafford
