[PATCH V2 2/3] mm: dmapool: Align to ARCH_DMA_MINALIGN in non-coherent DMA mode

In non-coherent DMA mode, kernel uses cache flushing operations to maintain I/O coherency, so the dmapool objects should be aligned to ARCH_DMA_MINALIGN. Cc: sta...@vger.kernel.org Signed-off-by: Huacai Chen --- mm/dmapool.c | 3 +++ 1 file changed, 3 insertions(+) diff
