[mm PATCH v2 20/26] arch/sparc: Add option to skip DMA sync as a part of map and unmap

This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to avoid invoking cache line invalidation if the driver will just handle it via a sync_for_cpu or sync_for_device call. Cc: "David S. Miller" Cc: sparcli...@vger.kernel.org Signed-off-by: Alexander Duyck
