 *
 * 29-Jan-87 -- rsp (Ricky Palmer)

 *	This change undoes the temporary change put in by Fred Canter
 *	on 15-Sep-16.  The TZK50 driver now handles nbufio.
 *
 * 15-Sep-86 -- fred (Fred Canter)
 *	TEMPORARY CHANGE: remove ststrategy entry from cdevsw, to disable
 *	nbufio for VAXstar TZK50 driver until the driver can be fixed.
 *	This will allow the base-level I TK50 kit to install on VAXstar.

 *  5-Aug-86  -- fred (Fred Canter)
 *	Changed st to stc and misc. other VAXstar changes.
 *
 * 23-Jul-86  -- prs
 *	Added the genericconf table. This table needs to be built here
 *	because only configured devices can be in the table. Also if
 *	no uba's or mba's are configured, then set ubdinit and mbdinit
 *	structure pointers to NULL so swapgeneric, swapboot, and machdep
 *	won't complain.
 *
 *  2-Jul-86  -- fred (Fred Canter)
 *	Added more VAXstar devices to cdevsw[] (sg sm sh).
 *	Added dummy ??driver symbols to satisfy reference in ka630.c
 *	if the device is not configured.
 *
 * 18-Jun-86  -- fred (Fred Canter)
 *	Changes for VAXstar kernel support.
 *
 * 5-Jun-86   -- jaw 	changes to config.
 *
 * 15-Apr-86 -- afd
 *	Changed "v_console" to "v_consputc".
 *	Added definition of "v_consgetc" for qvss and qdss input.
 *	These are no longer enclosed by "#ifdef MVAX". Since the symbols
 *	    are referenced in cons.o they must be defined for all cpus.
 *	There is also a dummy "contigphys()" to define the symbol.
 *
 * 02-Apr-86 -- jaw  add support for nautilus console and memory adapter
 *
 * 11-Mar-86
 *	add support for SAS memory driver
 *
 * 11-Mar-86 -- lp

 *
 * 12-Feb-86 -- jrs
 *	Move defn of null routine for buainit to bi dependency rather
 *	than 8200 cpu dependency.
 *
 * 03-Feb-86 -- jaw  for now define ka8200conf.
 *
 * 16-Jan-86 -- darrell
 *	removed the lines for the ka820machcheck, so it is not made
 *	as a psuedo device and defined it in cpuconf.c
 *
 * 20-Jan-86 -- Barb Glover
 *	Added error logger character device switch
 *
 * 01-Oct-85 -- Larry Cohen
 *	include ioctl.h so that window structure is defined.
 *
 * 03-Sep-85 -- jaw
 *	bi error interrupt added.
 *
 * 03-Aug-85 -- rjl
 *	added qdss and support to the microvax virtual console support.
 *
 * 21-Jun-85 -- jaw
 *	crx changes to cs...
 *
 * 19-Jun-85 -- jaw
 *	VAX8200 name change.
 *
 * 20-Mar-85 jaw
 *	add VAX8200 console storage device.
 *
 * 27-Feb-85 -tresvik
 *	Changes for support of the VAX8600 were merged in.
 *
 * 26 Nov 84 -- rjl
 *	Added the system console as major number 38. Major #0 becomes the
 *	system virtual console. When it's something other than the real
 *	console, the real console can be accessed as 38,0.
 *
 *	14-Nov-84	Stephen Reilly
 * 001- Added ioctl to disk driver which will be used for the disk partitioning
 *	scheme.
 *
 *	conf.c	6.1	83/07/29
