Enable optimization for nobounce_dmamap clients by setting the map held by the client to NULL. This allows the macros in bus.h to check against a constant to avoid function calls. Don't attempt to 'free()' contigmalloced pages in bus_dmamem_free(). We currently leak these pages, which is not ideal, but is better than a panic. The leak will be fixed when contigmalloc is merged into the bus dma framework after 3.0R. |
