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
