See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org The floppy drivers doesn't otherwise use the DMA API, so indirecting through it just for cache flushing in MIPS-specific code just call dma_cache_wback_inv directly.
