[PATCHv6 0/7] ARM: DMA-mapping framework redesign

[Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>]

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.


History of the development:

v1: (initial version of the DMA-mapping redesign patches):
