  Modified files:
    sys/powerpc/powerpc  busdma_machdep.c 
  Log:
  Reimplement bus_dmamap_load with bus_dmamap_load_buffer.
  Previously it didn't honor parent dma tag's restrictions such that
  an invalid dma segment could be passed to device. The driver for the
  device may panic in sanity check routine for the dma segment or may
  produce unexpected results. I have no idea how it could ever have
  worked before.
