[GIT PULL] DMA-mapping fixes for v3.6

[Marek Szyprowski]

Hi Linus,

I would like to ask for pulling another set of fixes for ARM dma-mapping
subsystem. Commit e9da6e9905e6 replaced custom consistent buffer
remapping code with generic vmalloc areas. It however introduced some
regressions caused by limited support for allocations in atomic context.
This series contains fixes for those regressions. For some subplatforms
the default, pre-allocated pool for atomic allocations turned out to be
too small, so a function for setting its size has been added. Another
set of patches adds support for atomic allocations to IOMMU-aware
DMA-mapping implementation. The last part of this pull request contains
two fixes for Contiguous Memory Allocator, which relax too strict
requirements.

The following changes since commit fea7a08acb13524b47711625eebea40a0ede69a0:

  Linux 3.6-rc3 (2012-08-22 13:29:06 -0700)
