 * HISTORY
 * $Log: machine.h,v $
 * Revision 1.1.1.1  1997/09/03 20:53:37  roland
 * Initial checkin of SGS release 244
 *
 *  2 July 1992	Mac Gillon at NeXT
 *	Changed HPPA subtypes to follow our practice. 
 *
 * 11 September 1992 David E. Bohman at NeXT
 *	Added CPU_SUBTYPE_486SX to the i386 family.
 *
 * 16 July 1992 David E. Bohman at NeXT
 *	Added CPU_SUBTYPE_586 to the i386 family.
 *
 * 17-Dec-91  Peter King (king) at NeXT
 *	Added support for the XXX_ALL subtypes.  These are used to
 *	tag object files that can run on any implementation of a
 *	particular family.
 *
 *  1-Mar-90  John Seamons (jks) at NeXT
 *	Redefined cpu_type and cpu_subtype definitions to indicate processor
 *	architecture instead of product types for the MC680x0.
 *
 * Revision 2.15  89/10/11  14:39:56  dlb
 * 	Removed should_exit - replaced by action thread.
 * 	[89/01/25            dlb]
 * 
 * Revision 2.14  89/07/14  17:21:39  rvb
 * 	Added CPU types and subtypes for MC68030, MC68040, MC88000,
 * 	HPPA, ARM and Sun4-SPARC.
 * 	[89/07/13            mrt]
 * 
 * Revision 2.12  89/05/30  10:38:58  rvb
 * 	Add R2000 machine types.
 * 	[89/05/30  08:28:53  rvb]
 * 
 * Revision 2.11  89/04/18  16:43:32  mwyoung
 * 	Use <machine/vm_types.h> rather than <vm/vm_param.h> to get
 * 	VM types.  Remove old history... none of it was insightful.
 * 
 * 	The variable declarations should be moved elsewhere.
 * 	[89/01/24            mwyoung]
