Jiri ended up acking v3 of the patches:

http://lists.infradead.org/pipermail/linux-arm-kernel/2013-September/200579.html

but I don't see them in -next. I'm happy to take them via my tree, just want
to make sure they don't conflict with anything you have planned for 3.13
and/or end up with our trees colliding in -next.

What's the plan?

Cheers,

Will
