Description: Debug DMA scatter-gather usage

More info: Perform extra checking that callers of dma_map_sg() have respected the appropriate segment length/boundary limits for the given device when preparing DMA scatterlists. This is particularly likely to have been overlooked in cases where the dma_map_sg() API is used for general bulk mapping of pages rather than preparing literal scatter-gather descriptors, where there is a risk of unexpected behaviour from DMA API implementations if the scatterlist is technically out-of-spec. If unsure, say N.
