Stephen,

thanks for looking into it so fast. I prefer to include it and send it
with the other patches. Besides tegra, also imx, mvebu, and vexpress
required to move things around a bit, so I wait for the someone to
comment on their mach changes first.

For the final patch set, I guess your Signed-off on this is sufficient
to convince Olof or Russell to take it.
