Log Message:
Rework drm prime guts.
- Our faux struct sg_table is now just an array of _pages_, not of
bus dma segments.
- We handle bus dma segments only in the presence of an adult bus dma
tag.
- All bus dma hacks are once again confined to bus_dma_hacks.h, and
more neatly organized:
. bus_dmamem_export_pages translates bus dma segs to vm_page array
. bus_dmamem_import_pages translates vm_page array to bus dma segs
