Alright; anything I didn't reply to looks good to me.

I have no problem with this except for the small nitpicks I gave, but
would be tempted to delay this part for one more cycle as it's really
independant -- what do you think?

time-wise we're getting close to the merge window already (probably in 2
weeks), how confident are you in this?
I can take patches 8..11 in -next now and probably find some time to
test over next weekend, are we good?
