915907cc03 Detect if we're running on a Cyrix 486DLC and enable automatic cache
negation whenever we access memory between 640k and 1M.

Original code from NetBSD 1.0-BETA.  The exact origins are unclear but
Theo de Raadt, Charles, and Michael V. may have contributed to it.

0b6f9dbfcb Rewrote last vestige of code that used gs (copyinstr). The use of gs in
this routine caused problems for machines that don't set it up properly
before boot (such was the case on an EVEREX machine sitting next to me).

7b6e72a847 Make it possible to run lptcontrol on a printer port which does not
actually have a printer connected or online:
- MAKEDEV:		remove all signs of lpa
			add lpctl? devices (minor # = unit + 128)
- usr.sbin/Makefile	add lptcontrol
- sys/i386/isa/lpt.c	implement the LP_BYPASS flag: when a unit is
			opened with this flag set, the printer is
			not primed, and no check is made to see that
			the printer is online.  This can only be used
			to pass ioctls.  (giving us /dev/lpctl?)
- lptcontrol.c		use /dev/lpctl? (LP_BYPASS)
			-f flag removed, -u flag added
- lptcontrol.8		document changes in lptcontrol
			rewrite using mandoc macros

Update the if_ep driver for the 3C579 and bring over some of the
changes from the netbsd driver.
This is not complete: the detection of the irq in the eisa does not
work and sometimes the reset for the 3C509 in ISA in an EISA bus system
don't work ( Need a hard reset to be found again == reset knob).

5f18a711b2 Newly implemented ioctls list:
DIOCGDINFO, DIOCGPART, DIOCWDINFO, DIOCSDINFO, CDIOCPLAYMSF, CDIOCRESET,
CDIOCEJECT.

CDIOCPLAYBLOCKS removed (old implementation completely wrong and I don't
know how to implement it correctly).

All routines now detects media change correctly.

DELAY_GETREPLAY increased for long time access from first track
to last.

mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs
of machine speed.

mcd_doread() now uses real status (old code uses obsoleted soft copy of it).

clear XBSY on error in mcd_doread()

mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()

optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.

call getdisklabel() _after_ mcdsize() for proper sizes

mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.

Do nothing on stray interrupt (which sometimes occurse, because driver
read data block too slow, DOS driver use 'insb' here). Old stray code
cause timeouts.

Read toc entries code rewritten to return many requested entries
(as supposed) instead of one entry with incorrect structure.

CMDREAD2 requests covered with disable_intr()/enable_intr()
(from DOS driver)

Read junk code added after read block code in doread (from DOS driver)

mcd_read_toc() code fixed to read all needed entries, old code cause
some audio tracks is not played.

mcd_playtracks() code fixed to proper check valid track range.

New binary read modes implemented (from DOS driver).

1) if_ie.c:
	Changed a printf and put a space in it. Formerly the "<3C507>"
	confused the syslog. He tried to see that as the priority to
	log that message.

2) isa_device.h:
	Changed the iobase variable from short to u_short. EISA
	Adresses can go up to 0xf000 and the sign extension doesn't
	look good in the probe output. Example:
	ep1 at 0xffff8000-0xffff8000f is not good :-), i like more a
	ep1 at 0x8000-0x8000f.

3) isa.c:
	Changed a string constant from "probe" to "prob", it gets
	later already an "ed" tagged on the end.

16e35aa368 Fixed bug caused by change of rlimit variables to quad_t's. The bug was in
using min() to calculate the minimum of rss_cur,rss_max - since these
are now quad_t's and min() takes u_ints...the comparison later for exceeding
the rss limit was always true - resulting in rather serious page thrashing.
Now using new qmin() function for this purpose.

Fixed another bug where PG_BUSY pages would sometimes be paged out (bad!).
This was caused by the PG_BUSY flag not being included in a comparison.
