    We added BUS_DMA_COHERENT to the API just before shipping 5.1. It
    is only a "hint", so if you need to verify that the implementation
    was able to give you coherent memory, we should add an API to allow
    you to know. Of course, the Sparc bus dma implementation doesn't honor
    the flag yet, but I'm sure that will change shortly.
