Wei and I discussed this IRL, the concern was the outstanding colopre
patches.

However I did a test apply on top of    
https://github.com/macrosheep/xen.git#colo/colo-v9 (the latest colopre)
and there were no rejects due to the remus refactoring.

There were rejects because I already applied 4/4 on Friday, i.e. they
were the inverse of what I fixed up then.

So given the lack of interaction with colopre Wei gave me permission to
go ahead, so I have applied patches 1..3.

4 was applied already, of course.

Ian.
