Oops, I was wrong.  Not sure what happened to my grep-fu, but it is
clearly set in multi_v7_defconfig in linux-3.10.y.

Awesome, thanks.  That confirms I was wrong :)

On a broader topic, if we have users in the field running v3.10.y on ARM

boot-test those systems.

I'll see if I can generate a list of patches.
