Log Message:
Support functions to map/unmap guest's memory into our kernel VM space.
This will be used by the block and network back-end.
The caller provide a list of machine address pages, and we return the
address virtual address they've been mapped to. These mapping are not
registered to the pmap (we don't have physical addresses for these pages),
so change bus_dma(9) to handle these mappings as well.
