um, why?

If you merge this into linux-next then it will trash already-merged patches
in -mm and, more particularly, it will trash other trees which you aren't
looking at, causing Stephen problems.

The way to merge this code is to get the base patches into mainline and
then trickle the dependent patches into subsystem trees, or direct into
mainline after the subsystem trees have merged, and with suitable acks.

You aren't set up to do that?
