[PATCH 09/18] sgiwd93: convert to dma_alloc_noncoherent
Use the new non-coherent DMA API including proper ownership transfers. This also means we can allocate the memory as DMA_TO_DEVICE instead of bidirectional.

a saner API for allocating DMA addressable pages v3
Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported. As a follow up I
