Hi,
This is another revision of the series to properly add atomic allocations for arm64. This version mostly addressed review comments. As always, reviews and testing welcome
Thanks, Laura
v4: Addressed comments from Thierry and Catalin. Updated map_vm_area call in dma_common_pages_remap since the API changed.
v3: Now a patch series due to refactoring of arm code. arm and arm64 now both use genalloc for atomic pool management. genalloc extensions added. DMA remapping code factored out as well.
v2: Various bug fixes pointed out by David and Ritesh (CMA dependency, swapping coherent, noncoherent). I'm still not sure how to address the devicetree suggestion by Will [1][2]. I added the devicetree mailing list this time around to get more input on this.

Laura Abbott (5): lib/genalloc.c: Add power aligned algorithm lib/genalloc.c: Add genpool range check function common: dma-mapping: Introduce common remapping functions arm: use genalloc for the atomic pool arm64: Add atomic pool for non-coherent and CMA allocations.
