0e195446b7 Bug fixes and performance improvements from John Dyson and myself:
1) check va before clearing the page clean flag. Not doing so was
	causing the vnode pager error 5 messages when paging from
	NFS. (pmap.c)
2) put back interrupt protection in idle_loop. Bruce didn't think
	it was necessary, John insists that it is (and I agree). (swtch.s)
3) various improvements to the clustering code (vm_machdep.c). It's
	now enabled/used by default.
4) bad disk blocks are now handled properly when doing clustered IOs.
	(wd.c, vm_machdep.c)
5) bogus bad block handling fixed in wd.c.
6) algorithm improvements to the pageout/pagescan daemons. It's amazing
	how well 4MB machines work now.

f690bbace7 Changes from John Dyson and myself:
1) Removed all instances of disable_intr()/enable_intr() and changed
	them back to splimp/splx. The previous method was done to improve
	the performance, but Bruces recent changes to inline spl* have
	made this unnecessary.
2) Cleaned up vm_machdep.c considerably. Probably fixed a few bugs, too.
3) Added a new mechanism for collecting page statistics - now done by
	a new system process "pagescan". Previously this was done by the
	pageout daemon, but this proved to be impractical.
4) Improved the page usage statistics gathering mechanism - performance is
	much improved in small memory machines.
5) Modified mbuf.h to enable the support for an external free routine when
	using mbuf clusters. Added appropriate glue in various places to
	allow this to work.
6) Adapted a suggested change to the NFS code from Yuval Yurom to take
	advantage of #5.
7) Added fault/swap statistics support.

a4392a014c Fixed brokeness in the support of the 83C790/Elite Ultra (now that I
finally have the f**king documentation!):

1) Changed all the numeric register offsets to symbolic ones (it should
	have been this way originally).
2) If 16 bit, disable the shared memory when not using it. Apparantly
	switching between 8/16bit mode makes the Ultra unhappy unless
	this is done (i.e. it trashes the bus).

ee5ae27f05 Changes to lpt driver:
- ansi prototypes in lpt.c
- a bit of tidying in lpt.c
- ioctl in lpt.c for switching between polling and using interrupts
- added lpt.h - needed for ioctl to allow switching between polling
        and interrupt-driven modes.

6ebe34f113 First pass at adding locale support. This code only deals with the LC_CTYPE
class of locale data, but could be extended to handle other locale
classes, as well as message catalogues and other non-locale i18n
support.

I have left the old _ctype_ array in place, and moved the ctype.h
header to octype.h, so that existing shared binaries will still be
able to find and use it as they require.

See /usr/src/share/locale for information on how to create new locale
data files (eventually this procedure will be improved).  I'd like to
have a family of locale files for various countries, languages, and
character sets, so please contribute some.

This code was originally written by Paul Borman and contributed to
4.4; I did the integration, and have somewhat tested it.  crt0.c
probably ought to call setlocale() if it doesn't already, but I'd like
for people to create some locale files and try things manually first
before I make every program do this.

fd59ff8180 CHANGES from Bruce:
---
This list of changes is in approximately chronological order (oldest first).

	o Many cosmetic changes - renamed comintr1 -> siointr1, moved
	  things around and fixed whitespace.
	o Reduced SLIP latency (FRAME_END hack) from 20-30 ms to 16 ms
	  at 115200 bps (you won't notice the average 10 ms improvement
	  on slow lines).  ppp seems to use only counted transfers so
	  there's no similar hack available.  It's too hard for the
	  driver to know the count.
	o Temporary #ifdefs for new and old interrupt handling
	  (OLD_INTERRUPT_HANDLING decided by setsofttty() not being
	  externally defined.
	o Don't test for the IIR_NOPEND bit being set - test for the
	  non-fifo part of the iir equalling it like the docs say to.
	  States with other IIR_NOPEND set in combination with the
	  other iir bits are undefined.  The docs may be stupid - the
	  old test would not have broken when the fifo bits were
	  introduced.
	o Noted more problems with DTR wait.
	o Rewrote console stuff.  Still some initialization and state
	  preservation problems.  Same for kgdb stuff.  The driver
	  doesn't do anything about the console close bug.  It needs
	  to be fixed entirely in i386/cons.c.  I like chmr's version
	  where the the console driver revectors the device open and
	  close routines.
	o Temporary (?) #ifdefs for references to tty buffers.
	o Noted further things to do in (2 comments about 3 places) for
	  phk's change to not touch RTS unless it is being used for flow
	  control.
	o Temporary #ifdefs for timestamp handling.  It needs fixing.
	  The microtime() call breaks the first rule of writing fast
	  interrupt handlers: NO calls to functions that might do slow
	  and bad things.  microtime() enables interrupts.  This turns
	  out to be only moderately harmful.  Also, I want the timestamp
	  copy outside of the normal interrupt handler.
	o Don't init com->tp early for the !DONT_MALLOC_TTYS case -
	  both sides are NULL.
	o Worry about com->tp == NULL in siopoll.  I don't see how you
	  survived the (incc <= 0 || !(tp->state & TS_ISOPEN)) test.
	  Perhaps early sttys or comcontrols set up the tp's for _all_
	  the ports before this code is reached.

d230622648 New interrupt code from Bruce Evans. In additional to Bruce's attached
list of changes, I've made the following additional changes:

1) i386/include/ipl.h renamed to spl.h as the name conflicts with the
   file of the same name in i386/isa/ipl.h.
2) changed all use of *mask (i.e. netmask, biomask, ttymask, etc) to
   *_imask (net_imask, etc).
3) changed vestige of splnet use in if_is to splimp.
4) got rid of "impmask" completely (Bruce had gotten rid of netmask),
   and are now using net_imask instead.
5) dozens of minor cruft to glue in Bruce's changes.

   These require changes I made to config(8) as well, and thus it must
be rebuilt.

-DG

from Bruce Evans:

sio:
	o No diff is supplied.  Remove the define of setsofttty().  I hope
	  that is enough.

*.s:
	o i386/isa/debug.h no longer exists.  The event counters became too
	  much trouble to maintain.  All function call entry and exception
	  entry counters can be recovered by using profiling kernel (the new
	  profiling supports all entry points; however, it is too slow to
	  leave enabled all the time; it also).  Only BDBTRAP() from debug.h
	  is now used.  That is moved to exception.s.  It might be worth
	  preserving SHOW_BITS() and calling it from _mcount() (if enabled).
	o T_ASTFLT is now only set just before calling trap().
	o All exception handlers set SWI_AST_MASK in cpl as soon as possible
	  after entry and arrange for _doreti to restore it atomically with
	  exiting.  It is not possible to set it atomically with entering
	  the kernel, so it must be checked against the user mode bits in
	  the trap frame before committing to using it.  There is no place
	  to store the old value of cpl for syscalls or traps, so there are
	  some complications restoring it.

Profiling stuff (mostly in *.s):
	o Changes to kern/subr_mcount.c, gcc and gprof are not supplied yet.
	o All interesting labels `foo' are renamed `_foo' and all
	  uninteresting labels `_bar' are renamed `bar'.  A small change
	  to gprof allows ignoring labels not starting with underscores.
	o MCOUNT_LABEL() is to provide names for counters for times spent
	  in exception handlers.
	o FAKE_MCOUNT() is a version of MCOUNT() suitable for exception
	  handlers.  Its arg is the pc where the exception occurred.  The
	  new mcount() pretends that this was a call from that pc to a
	  suitable MCOUNT_LABEL().
	o MEXITCOUNT is to turn off any timer started by MCOUNT().

/usr/src/sys/i386/i386/exception.s:
	o The non-BDB BPTTRAP() macros were doing a sti even when interrupts
	  were disabled when the trap occurred.  The sti (fixed) sti is
	  actually a no-op unless you have my changes to machdep.c that make
	  the debugger trap gates interrupt gates, but fixing that would
	  make the ifdefs messier.  ddb seems to be unharmed by both
	  interrupts always disabled and always enabled (I had the branch in
	  the fix back to front for some time :-().
	o There is no known pushal bug.
	o tf_err can be left as garbage for syscalls.

/usr/src/sys/i386/i386/locore.s:
	o Fix and update BDE_DEBUGGER support.
	o ENTRY(btext) before initialization was dangerous.
	o Warm boot shot was longer than intended.

/usr/src/sys/i386/i386/machdep.c:
	o DON'T APPLY ALL OF THIS DIFF.  It's what I'm using, but may require
	  other changes.
	  Use the following:
		o Remove aston() and setsoftclock().
	  Maybe use the following:
		o No netisr.h.
		o Spelling fix.
		o Delay to read the Rebooting message.
		o Fix for vm system unmapping a reduced area of memory
		  after bounds_check_with_label() reduces the size of
		  a physical i/o for a partition boundary.  A similar
		  fix is required in kern_physio.c.
		o Correct use of __CONCAT.  It never worked here for non-
		  ANSI cpp's.  Is it time to drop support for non-ANSI?
		o gdt_segs init.  0xffffffffUL is bogus because ssd_limit
		  is not 32 bits.  The replacement may have the same
		  value :-), but is more natural.
		o physmem was one page too low.  Confusing variable names.
	  Don't use the following:
		o Better numbers of buffers.  Each 8K page requires up to
		  16 buffer headers.  On my system, this results in 5576
		  buffers containing [up to] 2854912 bytes of memory.
		  The usual allocation of about 384 buffers only holds
		  192K of disk if you use it on an fs with a block size
		  of 512.
		o gdt changes for bdb.
		o *TGT -> *IDT changes for bdb.
		o #ifdefed changes for bdb.

/usr/src/sys/i386/i386/microtime.s:
	o Use the correct asm macros.  I think asm.h was copied from Mach
	  just for microtime and isn't used now.  It certainly doesn't
	  belong in <sys>.  Various macros are also duplicated in
	  sys/i386/boot.h and libc/i386/*.h.
	o Don't switch to and from the IRR; it is guaranteed to be selected
	  (default after ICU init and explicitly selected in isa.c too, and
	  never changed until the old microtime clobbered it).

/usr/src/sys/i386/i386/support.s:
	o Non-essential changes (none related to spls or profiling).
	o Removed slow loads of %gs again.  The LDT support may require
	  not relying on %gs, but loading it is not the way to fix it!
	  Some places (copyin ...) forgot to load it.  Loading it clobbers
	  the user %gs.  trap() still loads it after certain types of
	  faults so that fuword() etc can rely on it without loading it
	  explicitly.  Exception handlers don't restore it.  If we want
	  to preserve the user %gs, then the fastest method is to not
	  touch it except for context switches.  Comparing with
	  VM_MAXUSER_ADDRESS and branching takes only 2 or 4 cycles on
	  a 486, while loading %gs takes 9 cycles and using it takes
	  another.
	o Fixed a signed branch to unsigned.

/usr/src/sys/i386/i386/swtch.s:
	o Move spl0() outside of idle loop.
	o Remove cli/sti from idle loop.  sw1 does a cli, and in the
	  unlikely event of an interrupt occurring and whichqs becoming
	  zero, sw1 will just jump back to _idle.
	o There's no spl0() function in asm any more, so use splz().
	o swtch() doesn't need to be superaligned, at least with the
	  new mcounting.
	o Fixed a signed branch to unsigned.
	o Removed astoff().

/usr/src/sys/i386/i386/trap.c:
	o The decentralized extern decls were inconsistent, of course.
	o Fixed typo MATH_EMULTATE in comments. */
	o Removed unused variables.
	o Old netmask is now impmask; print it instead.  Perhaps we
	  should print some of the new masks.
	o BTW, trap() should not print anything for normal debugger
	  traps.

/usr/src/sys/i386/include/asmacros.h:
	o DON'T APPLY ALL OF THIS DIFF.  Just use some of the null macros
	  as necessary.

/usr/src/sys/i386/include/cpu.h:
	o CLKF_BASEPRI() changes since cpl == SWI_AST_MASK is now normal
	  while the kernel is running.
	o Don't use var++ to set boolean variables.  It fails after a mere
	  4G times :-) and is slower than storing a constant on [3-4]86s.

/usr/src/sys/i386/include/cpufunc.h:
	o DON'T APPLY ALL OF THIS DIFF.  You need mainly the include of
	  <machine/ipl.h>.  Unfortunately, <machine/ipl.h> is needed by
	  almost everything for the inlines.

/usr/src/sys/i386/include/ipl.h:
	o New file.  Defines spl inlines and SWI macros and declares most
	  variables related to hard and soft interrupt masks.

/usr/src/sys/i386/isa/icu.h:
	o Moved definitions to <machine/ipl.h>

/usr/src/sys/i386/isa/icu.s:
	o Software interrupts (SWIs) and delayed hardware interrupts (HWIs)
	  are now handled uniformally, and dispatching them from splx() is
	  more like dispatching them from _doreti.  The dispatcher is
	  essentially *(handler[ffs(ipending & ~cpl)]().
	o More care (not quite enough) is taken to avoid unbounded nesting
	  of interrupts.
	o The interface to softclock() is changed so that a trap frame is
	  not required.
	o Fast interrupt handlers are now handled more uniformally.
	  Configuration is still too early (new handlers would require
	  bits in <machine/ipl.h> and functions to vector.s).
	o splnnn() and splx() are no longer here; they are inline functions
	  (could be macros for other compilers).  splz() is the nontrivial
	  part of the old splx().

/usr/src/sys/i386/isa/ipl.h
	o New file.  Supposed to have only bus-dependent stuff.  Perhaps
	  the h/w masks should be declared here.

/usr/src/sys/i386/isa/isa.c:
	o DON'T APPLY ALL OF THIS DIFF.  You need only things involving
	  *mask and *MASK and comments about them.  netmask is now a pure
	  software mask.  It works like the softclock mask.

/usr/src/sys/i386/isa/vector.s:
	o Reorganize AUTO_EOI* macros.
	o Option FAST_INTR_HANDLER_USERS_ES for people who don't trust
	  fastintr handlers.
	o fastintr handlers need to metamorphose into ordinary interrupt
	  handlers if their SWI bit has become set.  Previously, sio had
	  unintended latency for handling output completions and input
	  of SLIP framing characters because this was not done.

/usr/src/sys/net/netisr.h:
	o The machine-dependent stuff is now imported from <machine/ipl.h>.

/usr/src/sys/sys/systm.h
	o DON'T APPLY ALL OF THIS DIFF.  You need mainly the different
	  splx() prototype.  The spl*() prototypes are duplicated as
	  inlines in <machine/ipl.h> but they need to be duplicated here
	  in case there are no inlines.  I sent systm.h and cpufunc.h
	  to Garrett.  We agree that spl0 should be replaced by splnone
	  and not the other way around like I've done.

/usr/src/sys/kern/kern_clock.c
	o splsoftclock() now lowers cpl so the direct call to softclock()
	  works as intended.
	o softclock() interface changed to avoid passing the whole frame
	  (some machines may need another change for profile_tick()).
	o profiling renamed _profiling to avoid ANSI namespace pollution.
	  (I had to improve the mcount() interface and may as well fix it.)
	  The GUPROF variant doesn't actually reference profiling here,
	  but the 'U' in GUPROF should mean to select the microtimer
	  mcount() and not change the interface.

068a409099 Beginning of change set for making more friendly laptop configurations.
Changes _only_ take effect if `options LAPTOP' is set.

Note:  This one is distinctly dodgy. When my IDE drive spins back up from sleep
mode, it generates this `extra interrupt' condition by spinning back up and
generating an intr, though without any particular action required.  This
message coming out every time is rather annoying, and thus disabled.
However, what I'm not at all sure of is whether or not all IDE drives will
behave in the same way, or if perhaps it needs to be done in a more complicated
fashion by detecting this more involved "I've spun up and am just saying hi"
condition.  This is a simple change and easy to back out/ammend if anybody has
any better ideas.

563ac84861 Added more status bytes for the mitsumi drive. This is only an ugly
hack in the moment for testing purposes and to get the drive going
again.
0x20 means empty drive.
0x30 means closed drive with CDROM inserted.
0x80 means drive pulled out, but door closed.
0xa0 means drive pulled out and door open.
Luckily none of these values are the same as that reported for Ethernet
cards ( 0 for WD8003E, 0x40 for WD8013EPC, 0x60 for NE2000).
The bad part is, the probe code gets the WD8003E so hosed, that it is
no longer usable after it. No problem with the WD8013EPC.

pseudo device pty xx still keeps its meaning: a maximum of

The changes are inspired by the way NetBSD did it (thanks for that!),
though I made it slihghtly different, including the interface so
at least 75% of the allocated space is deallocated when the tty is
closed.
Note further that it is easy to modify the ringbuffer length runtime.

Subject: cache botch in bootstrap
Date: Sun, 20 Feb 94 18:14:35 +1100
The cache in the bootstrap loader didn't allow for the device changing.

This caused surprisingly little trouble - the cache is only for a single
track (or part of a track), and the first access to a new device is
always for an early sector, so there is no problem unless the last access
to the old device was for an early sector.  I saw the problem on a system
with BSD on wd1 and no label on wd0.  Everything worked if the the device
name wd(1,a) was specified before the default of wd(0,a) was tried, but
when the default was tried, it failed on the first sector because there
was no label, and then the first sector on wd0 was always used instead
of the first sector on wd1, so there was apparently no label on wd1
either.

Description:
The integer overflow instruction (into) and the interrupt instruction with
value 4 (int #4) both give rise to SIGBUS signals rather than SIGFPE.  The
problem is that overflow is a trap not a fault (unlike the BOUND instruction).

768e8947c6 From: bde@kralizec.zeta.org.au (Bruce Evans)
o merged and fixed timeout code from sos.
	o merged DOS partition support from sos.
	o fixed "extra" interrupts.
	o check if malloc retuns NULL :-(.
	o print drive size as in NetBSD
	o after an error, return the residual count, not 0.
	o give up early for > 16 heads.
	o cleaned up the old-drive detection in wdgetctlr().
	o rewrote wddump().  I'd been putting this off because
	  I'd had the dump disabled since 0.0 and had no idea
	  if even the standard version worked.  It didn't:
	  (0) syscons' sgetc() interface broke some keyboard
	  stuff.
	  (1) CADDR1 is mapped using pmap() and pmap got a NULL
	  pointer trap (at least when I got to wddump() using
	  call diediedie from ddb) because the pte for CADDR1
	  is only supposed to be hacked on directly (e.g. in
	  physcopyseg()).
	  (2) bad144 handling was not done.
	  (3) it was slooow (3600 sectors/minute) because my
	  controller doesn't cache writes.
	o miscellaneous other cleanups, e.g., removed scattered
	  patchkit/terry dates.
	o lots of reformatting.

To be done:
	o Merge/fix TIH/NetBSD bad144 code (doesn't belong in any
	  particular driver.  Why aren't we using i386/dkbad.c?).
	o Merge/fix Dyson/NetBSD clustering code (large parts
	  should be shared).
	o Fix/extend the partition in use bits.  Support extended
	  partitions.  This should be shared by all disk drivers.  Swap
	  to a DOS partition so that the swap space can be shared with
	  linux.
	o Don't use polling except for initialization.  Need to
	  reorganise the state machine.  Then "extra" interrupts
	  shouldn't happen (except maybe one for initialization).
	o Fix disklabel, boot and driver inconsistencies with
	  bad144 in standard versions.
	o Look at latest linux clustering methods.  Our disksort()
	  gets in the way of clustering.
	o cleaned up the ATA changes (needs more work.  I think
	  the ATA specs say that the only thing really wrong with
	  the original version of wx is that there was no test
	  for drive-ready before some commands.  400 nsec delay
	  suffices for almost everything and 400 nsec delay is
	  usually "free").

6df720041a 1) Set ipending back to 4, because (16 + 4) bit not in
netmask or impmask.

2) Fixes from Bruce:
	o Changed name of schedsoftcom() to setsofttty() to match
	  setsoftclock()
	o Bool_t isn't used.
	o tx_fifo_size is 1 for chips without fifos, 16 for 16550's, to
	  help to output more efficiently for 16550's (LSR_TXRDY means
	  that the fifo is empty, not that it has space for one char).
	o Changed name of softsio1() to siopoll() and merged compoll()
	  into siopoll().
	o The probe forgot to clear com_mcr after it failed.  This is
	  harmful for 4 single serial ports on 2 interrupts.  It makes
	  partial misconfigurations worse.
	o Don't bother initializing static variables that are 0 (bidir
	  stuff).
	o Only initialize t_oflag to TTYDEF_OFLAG if unit == COMCONSOLE,
	  not if COMCONSOLE is defined.
	o Don't call siointr() from comparam() if there is no output in
	  progress.  For the call from sioopen(), there's no output in
	  progress, and siointr() often saw silo overflows for stale
	  input because it was called before sioopen() discarded the
	  input.
	o Let ttselect() do the work for select(), so that the fixes for
	  ttselect() don't have to be duplicated in zillions of drivers.

3579d8917b Patch from dcjm@cs.ed.ac.uk (Dave Matthews)...
Yes, I know that IFADDR ioctl is supposed to be deprecated... Note
that the patch was modified by me to fit better into the driver. -DG

...

While porting CAP to 386bsd/pk0.2.4 and now to FreeBSD Release 1.0
I found a couple of bugs associated with the packet filter. Here
are the fixes.  I'm posting them here because they apply to
FreeBSD and 386bsd/pk0.2.4 and possibly to other *BSD.

The first occurs when using the packet filter to write raw
ethernet packets.  The header consisting of the sender and
destination addresses and the protocol is removed and later
added back on, but with the byte order of the protocol reversed.
The fix ensures that the byte order in the protocol field is
swapped when it is removed.

The second fix ensures that SIOCGIFADDR works for BPF as claimed
in the man pages, by adding it to the ed driver.  Similar fixes
will be needed for other ethernet drivers.

d6eb591433 Patch from Brian Smith (modified a little by me) to allow kernel config
file override to disable fifo on 16550s:

I bought a board with two 16550's, but one of those ports has a mouse
on it.  The sio driver always enables the fifo, which is a bad thing
for mice and X.  The mouse is jerky and hard to use.  The simple thing
is be to treat one of the ports as a non-fifo'ed UART, and I use the
flags option in my config file.

So, my config file has:
device      sio0    at isa? port "IO_COM1" tty irq 4 flags 0x2 vector siointr
device      sio1    at isa? port "IO_COM2" tty irq 3 vector siointr

following is a summary:

1) increased object cache back up to a more reasonable value.
2) removed old & bogus cruft from machdep.c (clearseg, copyseg,

3) inlined many functions in pmap.c
4) changed "load_cr3(rcr3())" into tlbflush() and made tlbflush inline
	assembly.
5) changed the way that modified pages are tracked - now vm_page struct
	is kept updated directly - no more scanning page tables.
6) removed lots of unnecessary spl's
7) removed old unused functions from pmap.c
8) removed all use of page_size, page_shift, page_mask variables - replaced
	with PAGE_ constants.
9) moved trunc/round_page, atop, ptoa, out of vm_param.h and into i386/
	include/param.h, and optimized them.
10) numerous changes to sys/vm/ swap_pager, vnode_pager, pageout, fault
	code to improve performance. LRU algorithm modified to be more
	effective, read ahead/behind values tuned for better performance,
	etc, etc...

1b9d391946 Much better fix for the hanging console problem. This one actually
works.

c77fe5808b Backed out previous commit as it requires additional kludges to work
completely, and it looks like syscons might solve the problem a
different way  (although what about serial consoles??).

e4794aea16 Brute-force fix for the "hanging console" problem. Simply _don't_ call
the device close routine. This works because the device close calls
the line discipline close (which only flushes the output buffers) and
the ttyclose() routine, which does little of nothing except screw with
the session and process group fields (which is what was causing all
the problems).

136cc9d5ef More sane AHA_RESET_TIMEOUT, from some testing by
Todd Pfaff <todd@flex.eng.mcmaster.ca> who was the person to report the
original problem on a 1542C.

ce1105630d Now prints ``on eisa'' if id_iobase >= 0x1000, and made a slight code
cleanup for the other 2 cases of ``on motherboard'' and ``on isa''.

3926f9e8f3 Added the correct typecast's to the untimeout calls. Added a missing
return statement in the probe. This should have fixed all compiler warnings.

a8e9d1d5b7 Increased TIMEOUT in wdwait from 2000 to 20000 since it seems many people
have needed to do this in order for the wd driver to work for them.

As reported on the -bugs list by some one, and confirmed by Julian:

> I increased AHA_RESET_TIMEOUT in aha1542.c from 1000 to 10000

2ae37484c6 System V IPC code from Danny Boulet, chewed on a bit by the NetBSD group

f707f734a6 Removed some more old unused code/comments. Added hack to "fix" the
problem with some chipsets (UMC) remapping the 'hole' memory even when
you've got 16MB. People were led to believe that since there was only
16MB of memory in the machine, that they were okay wrt the ISA DMA
limit. This hack simply causes the extra memory to be ignored if it
appears around the 16MB limit.

4b9f17c5b5 Improved algorithm that calculates the pages in the base memory - If the
BIOS says that the amount is *between* 0-640K, believe it.  Cleaned up
the comments a bit, removed some old cruff, etc.

7af948c9cc Changed the default 'reboot' routine from cpu_reset() to shutdown_nice().
If you want to disable the reboot feature, then re-define the keymap to
not have a RBT call.

Nate Williams
87965552ef Changed the default syscons keymap to have <CTL-ALT-ESC> enter the
debugger and <CTL-ALT-DEL> call the reboot command.

d64f660fac Improvements mostly from John Dyson, with a little bit from me.
* Removed pmap_is_wired
* added extra cli/sti protection in idle (swtch.s)
* slight code improvement in trap.c
* added lots of comments
* improved paging and other algorithms in VM system

26e25527db From Gary Clark II:
1. Fixed probe to work with FX mitsumi's.

2. Added some defines in prep for adding interupts and dma

e8f1fa7451 Updated the TODO file with missing things.
Changed the output of the isa probe routine, that only devices, that
have an IO address and are smaller than 0x100 to be on the motherboard.
The seagate SCSI adapter is an example of a card, that doesn't have
an IO address and works only memory mapped.

b06a5891b4 Added the support for the Toshiba ethernet cards. It is only
ifdef and not default, because, i don't know  if anyone else
is using this card.

e58072bda5 From ache:
Choose older MULTIPORT version, because lastest bde version
	not worked.
	Don't force HUPCL for bidirectional case.
From bde:
	Use bit (1 << (16 + 4)) in schedsoftcom() to avoid clash with
	non-serial h/w on IRQ4.
	Allow FIFO_TRIGGER in config.
	Clear com->mcr_image when clearing mcr for init of 4port.  The
	usual value MCR_IENABLE should have broken 4ports unless
	something happened to clear it later.
	Turn off interrupts as well as DTR after an error waiting for
	carrier (bidir dialin case).
	Drain fifo more carefully.
	Don't hang up if debugging.
	Rearrange siointr() -> siointr1() for multiport case for speed,
	lower latency and clarity.
	Use suser() to check perms.
	Provide missing splx() after failed perms checks.
	c_ispeed == 0 means c_ispeed = c_ospeed (POSIX).
	Set parameters (except speed) for c_ospeed == 0 as well as
	hanging up.
	Better initialization for console (fifo stuff...).
	Misc. cleanups.
	Fix dead hang if modem power is off.

1660308965 Add comment to MAX_SLOTS that it may need to be 16 and to check against
EISA spec.  Fixed off by one error in ahbprobe so that it can find an
aha1742 in slot 8 (now uses slot <= MAX_SLOT, instead of slot < 8).
