[PATCHv9 00/10] ARM: DMA-mapping framework redesign

[Marek Szyprowski]

Hello,

This is a quick update on dma-mapping redesign patches for ARM. I did
some minor fixes suggested by Arnd and extended commit messages for a
few patches. Like the previous version, the patches have been rebased 
onto latest Linux v3.4-rc3 which comes with dma_map_ops related
preparation changes.

The patches are also available on my git repository at:
git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git 3.4-rc3-arm-dma-v9

The code has been tested on Samsung Exynos4 'UniversalC210' and NURI
boards with IOMMU driver posted by KyongHo Cho. The integration patch
has been posted in the following thread:
