Thanks.

However this series doesn't have the shape for getting merged yet, I've 
been very quick with the additional patches descriptions and I have not 
revisited the descriptions of pre-existing patches.

I was expecting you to take over. By the way there's no hurry I guess, 
we are already in the middle of the merge window, Michael usually 
doesn't take any more non-fixes patches once the merge window is open, 
so that series will go in 6.4
