[net-next PATCH RFC 03/26] arch/arc: Add option to skip sync on DMA mapping

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 later via a sync_for_cpu or sync_for_device call. Cc: Vineet Gupta Cc: linux-snps-arc@lists.infradead.org Signed-off-by: Alexander Duyck --- arch/arc
