[Kenn H. <ke...@us...>]

Update of /cvsroot/linux-vax/kernel-2.4/drivers/vsbus
In directory usw-pr-cvs1:/tmp/cvs-serv25353/drivers/vsbus

Added Files:
	Makefile vsbus.c 
Log Message:
Bring forward all 2.2 work from before new year.  This should give us
all a (somewhat) bootable kernel.

#
# Makefile for the linux kernel.
#
# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here
# unless it's something special (ie not a .c file).
#
# Note 2! The CFLAGS definitions are now in the main makefile...
