[YAMAMOTO Takashi <yamt%netbsd.org@localhost>]

Module Name:    src
Committed By:   yamt
Date:           Sat Jun 12 17:14:55 UTC 2004

Modified Files:
        src/sys/arch/x86/x86: bus_dma.c

Log Message:
- introduce _bus_dmamap_load_paddr, which takes (paddr, size) and
  add the range to the map, and use it for _bus_dmamap_load_{buffer,mbuf}.
- _bus_dmamap_load_mbuf: in the case of M_EXT_PAGES, deal with vm_pages
  directly rather than doing pmap_extract on given kva.

as a side effect, do a segment coalescing and boundary checks for mbufs.
