Indeed I've been taking some (rather overdue) holiday the last couple of 
weeks, sorry I forgot to take a look at this version beforehand. From a 
quick skim, nothing stands out as objectionable; thanks for taking my 
suggestions on board!

At some point once this lands I'll have a go at using the new flags to 
improve iommu-dma bounce buffering, so if I do spot anything else while 
I'm in there I'm sure could clean it up myself.

Cheers,
Robin.
