Hi Thomas, Jason,

I've talked this over with Stephen and he'd be willing to create the
stable branch with patches 2, 4 and 8. That could serve as the basis
for both Tegra and Marvell.

Given that there are no cross-dependencies for any of the other patches
(that I'm aware of) it would probably be easier to take them through the
Marvell tree if Bjorn and Thomas (tglx) agree to Ack the patches.
