Hi Linus,

I would like to ask You for pulling an important bugfix patch set for
DMA-mapping subsystem for v3.8-rc7.

The following changes since commit 949db153b6466c6f7cad5a427ecea94985927311:

  xtensa: Provide dummy dma_mmap_coherent() and dma_get_sgtable() (2013-01-29 08:27:41 +0100)

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

This pull request contains important bugfix patches for 9 architectures,
which finally fixes broken allmodconfig builds introduced in v3.8-rc1.
Those architectures don't use dma_map_ops based implementation and
require manual update or additional dummy implementations of the missing
new dma-mapping api functions: dma_mmap_coherent and dma_get_sgtable.

Thanks!

Best regards
