dma-direct: retry allocations using GFP_DMA for small masks If an attempt to allocate memory succeeded, but isn't inside the supported DMA mask, retry the allocation with GFP_DMA set as a last resort. Based on the x86 code, but an off by one error in what is now dma_coherent_ok has been fixed vs the x86 code. Signed-off-by: Christoph Hellwig <hch@lst.de>
