Hi Linus,

I would like to ask You for pulling some fixes and extensions to ARM
dma-mapping subsystem for v3.9-rc1.

  Linux 3.8 (2013-02-18 15:58:34 -0800)

are available in the git repository at:

  git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git for-v3.9

for you to fetch changes up to d589829107c5528164a9b7dfe50d0001780865ed:

  ARM: DMA-mapping: fix memory leak in IOMMU dma-mapping implementation (2013-02-25 15:30:44 +0100)

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

This time all patches are related only to ARM DMA-mapping subsystem. The
main extension provided by this pull request is highmem support. Besides
that it contains a bunch of small bugfixes and cleanups.

Thanks!
