Subject: [PATCH -mm 0/3] unify dma_get_cache_alignment implementations

Now each architecture has the own dma_get_cache_alignment
implementation.

dma_get_cache_alignment returns the minimum DMA
alignment. Architectures defines 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 can be applied to -mm.
