Update of /cvsroot/src/sys/arch/i386/isa
In directory nb00:/tmp/cvs-serv20862

Modified Files:
        isa_machdep.c 
Log Message:
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.
