 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.
