Hello, This is another update on my works DMA-mapping framework redesign for ARM architecture. It includes a few minor cleanup and fixes since the last version posted by the end of December 2011. This patch series is now based on the generic, cross-arch dma-mapping redesign patches posted in the "[PATCH 00/14] DMA-mapping framework redesign preparation" thread: http://www.spinics.net/lists/linux-sh/msg09777.html All patches have been now rebased onto v3.3-rc2 kernel. All the code has been tested on Samsung Exynos4 'UniversalC210' board with IOMMU driver posted by KyongHo Cho.
