-Subject: scsi: dma-mapping: always provide dma_get_cache_alignment
-
-From: Christoph Hellwig <hch@lst.de>
-
-commit 860dd4424f344400b491b212ee4acb3a358ba9d9 upstream.
-
-Provide the dummy version of dma_get_cache_alignment that always returns
-1 even if CONFIG_HAS_DMA is not set, so that drivers and subsystems can
-use it without ifdefs.

-Subject: scsi: use dma_get_cache_alignment() as minimum DMA alignment
-
-From: Huacai Chen <chenhc@lemote.com>
-
-commit 90addc6b3c9cda0146fbd62a08e234c2b224a80c upstream.
-
-In non-coherent DMA mode, kernel uses cache flushing operations to
-maintain I/O coherency, so scsi's block queue should be aligned to the
-value returned by dma_get_cache_alignment().  Otherwise, If a DMA buffer
-and a kernel structure share a same cache line, and if the kernel
-structure has dirty data, cache_invalidate (no writeback) will cause
-data corruption.
