Thanks for the update.

I've applied all but this patch 3 now into the review-ilpo-fixes branch. 
As this patch is for-next material and I can only apply it once I've 
merged the fixes branch into the for-next branch somewhere later in the 
cycle (it'll sit in patchwork in the meantime, so I won't be forget
it :-)).
