Subject: [GIT PULL] CMA and DMA-mapping updates for v3.8

Hi Linus,

I would like to ask for pulling another set of Contiguous Memory Allocator and
DMA-mapping framework updates for v3.8.

The following changes since commit 29594404d7fe73cd80eaa4ee8c43dcc53970c60e:

  Linux 3.7 (2012-12-10 19:30:57 -0800)

are available in the git repository at:

  git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git for-v3.8

  drivers: cma: represent physical addresses as phys_addr_t (2012-12-11 09:28:09 +0100)

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

This pull request consists only of two patches. First fixes long standing
issue with dmapools (the code predates current GIT history), which forced all
allocations to use GFP_ATOMIC flag, ignoring the flags passed by the caller.
The second patch changes CMA code to correctly use phys_addr_t type what
enables support for LPAE systems.

Thanks!

Best regards
