This series of patches will speed up memory allocation in dma-mapping
quite a bit.

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 was going to ask what the next steps were for this series.
Presumably I could post the patch to Russell's patch tracker if folks
want me to do that.  Alternatively it could go through the ARM-SOC
tree?

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.

Right.  Both Robin and Tomasz gave their Reviewed-by to Patch #1 in v5
even after v6 was posted.

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.

Warning sounds good.

Typo in 4/5 changelog: "reqiurements"

Thanks for catching!


I'm happy to post up a v6 with these things fixed or I'm happy for
whoever is applying it to make these small fixes themselves.  Any
volunteers?  Olof, Arnd, or Russell: any of you want these patches?
