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.
