Hmm. I don't understand the issue here.

I don't recall the exact commits, but I ended up needing to base one of 
the branches on -rc2. So, I then based all the branches on the same 
commit. When I create Tegra's for-next, I start with that baseline 
branch and merge in each Tegra topic branch. That way, the merges only 
bring in exactly what's in that branch, and it's easy to validate the 
final result in gitk/similar. I suppose it'd work fine if I start with 
the newest base of any branch and then merged the topic branches in; 
that would at least restrict the merges to only the contents of the 
branch, although it'd create a far more difficult to validate history, 
since the different topic branches would be based in different places.

I had asked individual authors of the various defconfig changes to 
submit equivalent changes to multi_v7_defconfig, and I thought they had. 
I guess I'll take a look and see what's missing.
