- * HISTORY
- * $Log: machine.h,v $
- * 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]
