Re: [mm PATCH v2 18/26] arch/powerpc: Add option to skip DMA sync as a part of mapping

Alexander Duyck [off-list ref] writes:

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.
