From NetBSD:

- Fix pr sparc64/15633: datafault at tlp_start causes panic
- Also clean up some additional 32-bit kernel printf issues.
- Handle the case where a DMA operation wraps from the end of a page to the
beginning of the same page properly by double-mapping that page.
- Move a brace so this will compile w/o DEBUG.
- Overhaul iommu_dvmamap_load_raw().
From Me:
- Verify the streaming cache exists before waiting on it to clear during flush.
- Force sync of flush status (hardware sets it to 1 when its done)
- Force sync flush of registers (bus_space_barrier)
- Flush ALL segments on BUS_DMA_POSTREAD operations (not just the first!)
