[PATCH V7 2/2] scsi: Align block queue to dma_get_cache_alignment()

In non-coherent DMA mode, kernel uses cache flushing operations to maintain I/O coherency, so scsi's block queue should be aligned to ARCH_DMA_MINALIGN. Otherwise, it will cause data corruption, at least on MIPS: Step 1, dma_map_single Step 2, cache_invalidate (no writeback)

[PATCH V7 1/2] dma-mapping: Rework dma_get_cache_alignment()

Make dma_get_cache_alignment() to accept a 'dev' argument. As a result, it can return different alignments due to different devices' I/O cache coherency. Currently, MIPS is the only architecture which support coherent & non- coherent devices co-exist. This may be changed in the future, so add a ne
