From: "Aneesh Kumar K.V" <redacted> We want to use CMA for allocating hash page table and real mode area for PPC64. Hence move DMA contiguous related changes into a seperate config so that ppc64 can enable CMA without requiring DMA contiguous. Acked-by: Michal Nazarewicz <redacted> Acked-by: Paul Mackerras <redacted> Signed-off-by: Aneesh Kumar K.V <redacted>OK. It looks that there is not that much that can be easily shared between dma-mapping cma provider and ppc/kvm cma allocator. I would prefer to merge patch 1/4 to my dma-mapping tree, because I plan some significant changes in cma code, see: http://thread.gmane.org/gmane.linux.drivers.devicetree/40013/ I think it is better to keep those changes together. For now I've merged your patch with removed defconfig updates. AFAIK such changes require separate handling to avoid pointless merge conflicts.
How do we get the defconfig changes done ?
I've also prepared a topic branch for-v3.12-cma-dma, available at git://git.linaro.org/people/mszyprowski/linux-dma-mapping, which You can merge together with your changes to ppc kernel trees.
Thanks. Will update accordingly as other patches get picked into respective trees -aneesh
