/* ------------------------------------------------------------------------
 * Modification History:
 *
 * 31-Jan-89 -- map
 *	Change include syntax for merged pool.
 *
 * 18-Mar-86 -- jaw  add routines to cpu switch for nexus/unibus addreses
 *		     also got rid of some globals like nexnum.
 *
 * 27-Sep-85 -- tresvik
 *	Fixed reported bug - changed UMEMSIZE780 for 750 and 730
 *	to UMEMSIZE750 and UMEMSIZE730 respectively.  This broke builds
 *	for cpu specific kernels from source.
 *
 * 19-Jun-85 -- jaw
 *	VAX8200 name change.
 *
 * 14-Mar-85 -jaw
 *	Changes for support of the VAX8200.
 *
 * 12-Mar-85 -tresvik
 *	Reduced IOA count from 4 to 2 for the VAX8600
 *
 * 27-Feb-85 -tresvik
 *	Changes for support of the VAX8600 were merged in.
 *
 *  3 Nov 84 -- rjl
 *	Added support for MicroVAX-II
 *
 *  2 Jan 84 -- jmcg
 *	Added support for MicroVAX I.
 *
 *  2 Jan 84 --jmcg
 *	Derived from Ultrix-32 baseline sources 1.4, heritage is 4.2BSD
