DMA-mapping framework updates for v3.8.

The following changes since commit 29594404d7fe73cd80eaa4ee8c43dcc53970c60e:

  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.
