Christoph Hellwig ffcb754584 dma-mapping: reject __GFP_COMP in dma_alloc_attrs ... DMA allocations can never be turned back into a page pointer, so requesting compound pages doesn't make sense and it can't even be supported at all by various backends. Reject __GFP_COMP with a warning in dma_alloc_attrs, and stop clearing the flag in the arm dma ops and dma-iommu.
