Yes, I can take them if they work fine without the rest of the patches.

I could also take all the patches up to patch #6 via fbdev tree. Some of
the patches are for arch x86, but they seem to be still about
framebuffers. But maybe that causes conflicts with x86 tree, then =).

Then again, maybe we should just go forward and let Linus handle the
conflict. I'm planning to send the "normal" fbdev changes and the
fbdev-reorg separately (just in case Linus doesn't like the reorg), and
that already causes conflicts, very similar to what this series causes.

So in any case Linus has to handle that conflict, or use a resolution
offered by me. So if fbdev changes and this series are merged in
relatively early phase, I can then send the reorg series a bit later and
offer a conflict resolution that solves the conflicts for both series.

That way this series doesn't get delayed needlessly in the case that
Linus rejects the reorg series.
