Update of /cvsroot/src/sys/arch/bebox/bebox
In directory nb00:/tmp/cvs-serv20952

Modified Files:
        bus_dma.c 
Log Message:
Sync w/ i386 port:

When loading a DMA map, if the page's physical address exceeds the bounce
threshold, return an error to the caller (the caller will attempt to
bounce the transfer).

Update of /cvsroot/src/sys/arch/bebox/isa
In directory nb00:/tmp/cvs-serv20998

Modified Files:
        isadma_machdep.c 
Log Message:
Sync w/ i386 port:

Optimize the ISA DMA map load somewhat; don't traverse the buffer twice.
Instead, just attempt to do a normal load first.  If we exceed the bounce
threshold or the number of segments, then we bounce the transfer.

Remove the _cookie member of the DMA tag; it's not used by anything.  (This
was already done to the i386 port.)
