Thank you, Alex for your persistence with this patch series. Fee free to 
add my Acked-by to all the patches that don't already have my R-b. I 
have done pretty through reviews of previous versions of those patches, 
but obviously missed a lot of issues pointed out by real MM experts.

Thank you Alistair for your reviews, feedback and collaboration!
