  Log:
  MFC amd64:
    Consolidate all of the bounce tests into the BUS_DMA_COULD_BOUNCE flag.
    Allocate the bounce zone at either tag creation or map creation to help
    avoid null-pointer derefs later on.  Track total pages per zone so that
    each zone can get a minimum allocation at tag creation time instead of
    being defeated by mis-behaving tags that suck up the max amount.
