[Herb Peyerl <hpeyerl%netbsd.org@localhost>]

Module Name:    src
Committed By:   hpeyerl
Date:           Thu Nov 22 13:33:08 UTC 2007

Modified Files:
        src/sys/arch/powerpc/ibm4xx: trap.c

Log Message:
Optimize copyin/copyout to transfer as many words as possible before doing
residual bytes. This improves small transfers. As a result, we can avoid
doing bigcopyin/bigcopyout until len>1024 instead of len>256.
