From 4565f0170dfc849b3629c27d769db800467baa62 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Tue, 10 Aug 2010 18:03:22 -0700 Subject: dma-mapping: unify dma_get_cache_alignment implementations dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1. This patch also fixes this issue.
