Well, I guess for other reasons rebasing the Tegra tree is useful for a
few dependencies, so I'll drop that part of the patch which moves
v7_invalidate_l1() from one file to another, so there shouldn't be any
conflicts, and you can feel free to take this series through whatever
tree you want.

I haven't tested this patch yet though, to see whether the slight
differences in the code in your patch mentioned in the other sub-thread
affect Tegra at all. Hopefully I can test this later today.
