Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto).

Platforms will now have to supply a function dma_device_is_coherent which returns if a particular device participates in the coherence domain. For most platforms this function will always return 0 or 1. Signed-off-by: NRalf Baechle <ralf@linux-mips.org>
