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

[Gregory CLEMENT]

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.

Gregory
