Since we introduced the breakage in arm-soc, I've picked up the fix (I guess
it could have gone through Russell's tree as well though).

I've added the reference to the introducing commit, and the acks/review tags.

Adding a defconfig for a !MMU platform seems like a good idea, since there's
several of us who make sure that there is build coverage of the defconfigs and
follow up on most of the breakage. Feel free to send one in for 3.9.
