gross hack to get around the fact that there are currently devices with
...
common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support. As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.
