Hi, This is a series to add a pool for atomic allocations for arm64. It was previously suggested to try and share more code with arm. I did some refactoring to have arm use genalloc and pull out some of the remapping code. The end result is a negative diffstat overall for arm dma-mapping.c. There still might be some room for more refactoring of atomic functions into common dma-mapping.c and integration with dma-coherent.c but there should be less overlap now. Reviews and testing welcome. Thanks, Laura 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.
