Ping ? people OK if I take this via arc tree (after baking it in linux-next for
some time).

It makes more sense to add it to the arc tree than kbuild. If that's
what you are asking?
Thanks,

I haven't tested it, but this looks sane.
Acked-by: David Daney <david.daney@cavium.com>
I have no opinion about the path this should take towards Linus' tree.

Yep, that's what I was asking (and fishing for a ACK or two which I now have
thanks to David).
Patch added to ARC for-curr so it gets a decent -next exposure before sending over
to Linus in 3.13 cycle.
Thx,
