Thanks. After having a look at it seems concerning viafb to be mostly
Haralds patches with 1 or 2 extra ones.

Feel free to add the things you like. The main objective is probably to
get things working and stable. I do not have an idea how good that will
work out as I don't know how much code that requires. If you think
that's the way to go, then we'll try it and see whether it leads to
something usable and maintainable.

Jep, that's fine with me. I'll try to rebase&integrate the patches I
consider interesting from Harald's tree in -mm. I guess that's a good
thing to do as that's the latest used common base.
Any objections?
