As far as I can see we have all the necessary acks etc and it looks
good to me as well.

Shall I do an immutable branch with the whole lot or should we split it
up?  Patches 1 and 5 need to go through the same tree, but bindings
could go via another route.  I'm also fine if the whole lot goes
via the appropriate soc tree if that is easier.
