Subject: [GIT PULL] CMA and DMA-mapping updates for v3.7

Hi Linus,

I would like to ask for pulling another set of CMA and DMA-mapping framework
updates for v3.7.

The following changes since commit a0d271cbfed1dd50278c6b06bead3d00ba0a88f9:

  Linux 3.6 (2012-09-30 16:47:46 -0700)

are available in the git repository at:

  git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git for-v3.7

for you to fetch changes up to 461b6f0d3d7d4e556035463b531136b034b7433e:

  Merge branch 'next-cleanup' into for-v3.7 (2012-10-02 09:24:24 +0200)

----------------------------------------------------------------

This time the pull request is rather small, because the further redesign
patches were not ready on time.

This pull request consists of the patches which extend ARM DMA-mapping
subsystem with support for CPU coherent (ACP) DMA busses. The first
client of the new version is HighBank SATA driver. The second part of
the pull request includes various cleanup for both CMA common code and
ARM DMA-mapping subsystem.

Thanks!

Best regards
