Update of /cvsroot/src/sys/arch/amiga/amiga
In directory netbsd1:/var/slash-tmp/cvs-serv1253

Modified Files:
        vm_machdep.c 
Log Message:
Use the buffer length passed as a parameter to vmapbuf() and vunmapbuf()
instead of bp->b_bcount.  The I/O operation may have changed bp->b_bcount,
and not all of the kernel virtual memory will be freed.  This will result
in the VM system putting pages back on the free list which are still
mapped.   This may cause a deadlock later trying to enter pages into
the kernel pmap.  [See PR#4120 for more details.]
