Change 56789 by rwatson at rwatson_tislabs on 2004/07/08 18:04:24

	Reduce differences to add System V IPC MAC labeling and access
	control against CVS: don't introduce msg_msg.h, instead place the
	global definition of 'struct msg' in '#ifdef _KERNEL' of msg.h.
	Still not ideal name space wise, but is likely sufficient.
