Modified Files: src/share/man/man9: bus_dma.9 Log Message: bus_dma(9): Document BUS_DMA_PREFETCHABLE. Like BUS_DMA_NOCACHE. Doesn't absolve you of the need for bus_dmamap_sync, but if you later pass the vaddr to bus_dmamap_load, the DMA map might notice the mapping is write-combining and use this to make bus_dmamap_sync cheaper.
