0463028c37 Fix a problem with child inheritance of sysv shm. Problem brought
to my attention by Brad Lineberger <bil@mpgn.com> and Rob Miracle.

683cbdf4af Fixed spelling of new SC_KBD_PROBE_WORKS option in options.i386.
It worked because it is spelled correctly in LINT.

Added old obscure syscons options MAXCONS, SLOW_VGA and XT_KEYBOARD.
This file should be sorted both alphabetically and on the module
name by using a consistent prefix for each module, but there is no
consistency in the old options.  E.g., MAXCONS is spelled PCVT_NSCREENS
for pcvt.

9545a0eaa4 Hack workaround XFree86 switching failure when used with /dev/sysmouse
and xdm, possibly in general.

What was happening was that the server was doing a tcsetattr(.. TCSADRAIN)
on the mouse fd after a write.  Since /dev/sysmouse had a null t_oproc,
the drain failed with EIO.  Somehow this spammed XFree86 (!@&^#%*& binary
release!!), and the driver was left in a bogus state (ie: switch_in_progress
permanently TRUE).

The simplest way out was to implement a dummy scmousestart() routine to
accept any characters from the tty system and toss them into the void.

It would probably be more correct to intercept scwrite()'s to the mouse
device, but that's executed for every single write to the screen.
Supplying a start routine to eat the characters is only executed for the
mouse port during startup/shutdown, so it should be faster.

80f495ec7e Backed out last change. It depends on the future change of adding
-I- to CFLAGS.  <sb.h> must currently be used to give the version
of sb.h in the current directory, while "sb.h" in the buggy version
gave the (wrong) version in the source directory.  Searching in the
source directory first is normal, but is the reverse of the order
suggested by the 4.4Lite2 #include style.  -I- will remove the
ambiguities.

47382cd1e0 Make syscons replicate a mousesystems mouse on minor 128..
This enables other consumers of the mouse, to get it info via
moused/syscons.
In order to use it run moused (from sysconfig), and then tell
your Xserver that it should use /dev/sysmouse (mknod sysmouse c 12 128)
and it a mousesystems mouse. Everybody will be happy then :)
Remember that moused still needs to know what kind of mouse you
have..

6074a34497 Saved 48 bytes (46 before padding) using assorted nano-optimizations:
- avoiding strcmp("?" saved 12 bytes.  gcc inlined the strcmp()
  but this takes as much or more code as a function call.  The
  inlining was bogus because the strcmp() in the bootstrap isn't
  standard.

- using a char instead of an int for the boolean `last_only' saved 8
  bytes.  Booleans should usually be represented as chars on the i386.

- simplifying the return tests saved 9 bytes.

- using putc instead of printf to print a newline saved 3 bytes of code
  and 2 bytes of const data.

- avoiding `else's by always doing the else clause and fixing it up
  saved 4+8 bytes.

ae6e81ef56 Saved 48 bytes (56 before padding) by moving a variable declaration.
gcc always generates large code for accesses to globals.  For locals
it only generates large code if there are more than 128 bytes of
locals.  It sorts scalar locals after array locals to pessimize for
space in the usual case when there are more (static) references to
scalars than to arrays.

Saved another 16 bytes (13 before padding) by adding a `continue'.

Fall-through tests normally save space, but here one of them made
gcc do space-unoptimal register allocation (it allocates ch in %bl
because preserving this register across function calls is "free",
but comparisions with %bl take one byte fewer than comparsions with
%bl).

53809eab9c Add option SC_KBD_PROBE_WORKS to syscons driver.
If you define this, it means your keyboard is actually probable using the
brain-dammaged probe routine in syscons, and if the keyboard is NOT found,
then you don't want syscons to activate itself further.

bf709d2564 3 changes:
1/ Makefile:  the maximum size for boot2 is 7.5K not 7K,
so don't complain until it reaches THAT size..
newfs leaves 8K and boot 1 is 512k. leaving 7.5K becasue the disklabel
is considered to part of the boot2 file.

[512  boot1][512 disklabel][     7K boot2 code        ]
[boot1 file][               boot2 file                ]

2/ Boot2.S: move the soring of the default name read from block 2 to AFTER
clearing the BSS.

3/ boot.c:
Move the parsing of the command line into the
place it's called for clarity.. alsoi comment it a bit and clean it
up a bit.. for some reason this seems ot have made it a little
larger, but I can't work out why.. maybe bruce might have ideas?
compensated for by shrinkage elsewhere..

the practical result of this is htat the default string can now contain args
e.g. if you change the default string to have -gd
then the machine will boot to the dgb debugger stub by default..
this is mostly useful with the nextboot utility..
as it now allows you to remotely force a machine to reboot into
the debugger.

7fa8a688aa Add preliminary support for the Orion PCI chip set. It is special in the
way it attaches multiple PCI buses directly to the CPU, instead of having
them hanging off from PCI to PCI bridges. This code is a hack, and will
be obsoleted by the planned rework of the PCI code, which will change the
dealing with PCI to PCI bridges and other special devices significantly.

The patch also adds a kern_devconf entry for PCI bus 0 which is assumed
to be a child of cpu0. The new PCI code will make it possible to hand out
the kern_devconf structure to a pci device being attached, since this is
(regretably, IMHO) required by a few ISA devices.

Finally there are new PCI ids for some Intel chip set devices, which had
already been known to 2.1.5R, but did not make it into -current. This closes
"kern/1558: PCI probe seems to have lost a device in -current".

e3bc07db0d If the basemem value supplied by the bootblocks, differs from the value

'stolen by BIOS' memory in the same manner as the ISA-hole memory, since
it is really an extenstion of the BIOS.  This is necessary for 32-bit
BIOS functions such as APM support on laptops, and the loss of memory
for non-necessary functions seems to be at most 4k.

1de1c45200 Add some padding to struct ifmibdata and move the `struct ifdata' to
the end of that sstructure to make evolution easier.

Add definitions for the 802.3/Ethernet MIB.  To implement this, simply
add a `struct ifmib_iso_8802_3' somewhere in your interface's softc,
point if_linkmib to it, set if_linkmiblen, and fill in the statistics
with appropriate values.  (I didn't want to create Yet Another Ethernet-

62494ee3f3 Sorted and fixed tabs.
The only excuse this had for becoming misordered was that some drivers
were sorted on the driver name field, but the ffs versus mfs ordering
shows that this is not a consistent order.

The only case that I know of where simple sorting is wrong is for files
that must be compiled without profiling if profiling is configured and
normally otherwise.  Then the line with `profiling-routine' must appear
first to get the file compiled with ${PROFILE_C}.

b12e5e82b6 The socketpair(0 syscall is bogusly returning the fd numbers through
the primary and secondary return codes, causing it to not behave as
documented.  This probably originates from the ancient BSD kernels that
had pipe(2) implemented by socketpair(2), there are no binaries left that
we can run that do this.

6476c0d204 Even though this looks like it, this is not a complex code change.
The interface into the "VMIO" system has changed to be more consistant
and robust.  Essentially, it is now no longer necessary to call vn_open
to get merged VM/Buffer cache operation, and exceptional conditions
such as merged operation of VBLK devices is simpler and more correct.

This code corrects a potentially large set of problems including the
problems with ktrace output and loaded systems, file create/deletes,
etc.

Most of the changes to NFS are cosmetic and name changes, eliminating
a layer of subroutine calls.  The direct calls to vput/vrele have
been re-instituted for better cross platform compatibility.

I've been meaning to do this for AGES as I keep having to patch those routines

any module that assigns resources to processes needs to know when
these events occur. there are existsing modules that should be modified
to take advantage of these.. e.g. SYSV IPC primatives
presently have #ifdef entries in exit()
