[PATCH v2 0/2] Fix dma mapping when the cache is coherent

Hi,

These two patches fixes the dma mapping functions when the system is
cache coherent. The first one allows to fix an issue we have on Armada
375/38x with the PL310 that's why it is tagged for stable too.

The second one was suggested by Catalin. I put it in form and check
that it can be built, but I don't have the platform to test it, so it
definitely need someone to test it. I guess this one should also go to
the stable kernel but I don't know from which point.
