/*
 * Modification History:
 *
 * 4-Sep-90	dlh
 *	add defines for vector support
 *
 * 06-Jun-90 pmk
 *	Remove 	printf("#define\tCIADAP_SZ %d\n", sizeof(CIADAP));
 *
 * 09-Nov-89 jaw
 *	remove unused fields in vmmeter.
 *
 * 20-Jul-89 jaw
 *	rearrange lock structure.
 *
 *  10-Feb-89	jaw
 *	move TBI flag to sperate per-cpu field.
 *
 *  02-Feb-89	jaw
 *	Make longjmp mpsafe.  move newpc and newfp global to per-cpudata base.
 *
 *  26-Jan-89	jaw
 *	fix up start/stop cpu.
 *
 *  3-Jan-89	jmartin
 *	#define BITPOS et al; invoke for c_intrans and c_free fields.
 *
 * 18-Jul-88	jaa
 *	removed #define of USRPTSIZE
 *
 * 13-Jun-88 -- chet
 *	add configurable buffer cache changes
 *
 * 8-Mar-88 jaa
 *	ifdef'd USRPTSIZE
 *
 * 2-Feb-88 tresvik
 *	if building a STANDALONE KERNEL, add NMD (Memory Device) pages
 *	to the value of SYSPTSIZE
 *
 * 15-Jan-88 lp
 *	NMBCLUSTERS is gone.
 *
 * 05-Jan-88 -- Larry Cohen
 *	Increase SYSPTSIZE so standalone kernels will boot.
 *
 * 13-Feb-87 -- Chase
 *	Increase size of mbuf map.  This change will consume an additional
 *	2k of memory on every system, but it should eliminate system panics
 *	caused by running out of mbuf map.
 *
 * 16-Jul-86 -- Todd M. Katz
 *	Add definition for CIADAP_SZ, the size of a CI adapter structure.
 *
 * 14-Apr-86 -- jaw
 *	remove MAXNUBA referances.....use NUBA only!
 *
 * 02-Apr-86 -- jrs
 *	Removed NQ stuff added in previous (defunct) scheduler
 *
 * 11-Mar-86 -- Larry
 *	NMBCLUSTERS is now a function of MAXUSERS
 *
 * 05-Mar-86 -- bglover
 *	Removed msgbuf from kernel; replaced with error log buffer
 *
 * 03-Mar-86 -- jrs
 *	Add in rpb offsets needed to fill in slave start code
 *
 * 05-Feb-86 -- jrs
 *	Add c_paddr cpudata structure offset
 *
 * 04-feb-86 -- jaw  get rid of biic.h.
 *
 * 22-Jul-85 -- jrs
 *	Add cpudata structure offsets for multiprocessor work
 *
 * 31 Jun 85	darrell
 *	Added a lines to define UH_ZVCNT and UH_ZVFLG to make those
 *	elements of the uba_hd structure available to macro code (locore.s).
 *
 * 19-Jun-85 -- jaw
 *	VAX8200 name change.
 *
 * 13-Mar-85 -jaw
 *	Changes for support of the VAX8200 were merged in.
 *
 * 27-Feb-85 -tresvik
 *	Changes for support of the VAX8600 were merged in.
