This is pretty much all ARM and driver stuff so I think I'll duck it. 
But I can merge it if nobody else feels a need to.

I saw a few acked-by/tested-by/etc from the v5 posting which weren't
carried over into v6 (might have been a timing race), so please fix
that up if there's an opportunity.

Regarding the new DMA_ATTR_ALLOC_SINGLE_PAGES hint: I suggest adding
"DMA_ATTR_ALLOC_SINGLE_PAGES is presently implemented only on ARM" to
the docs.  Or perhaps have a shot at implementing it elsewhere.

Typo in 4/5 changelog: "reqiurements"
