Thanks. I applied patches 1-5, 10 and 11 to the block branch, i.e.
leaving out the transfer rate stuff. I believe this is fairly
independent so it makes sense to apply the rest of the series without
it, but if you think I should dequeue all of the patches, let me know.

The main reason for not applying 6-9 is that I think migration is
broken, but I'll wait for Juan and/or Paolo to confirm. If a respin is
required, you can also fix the three default machine types.
