8159bae9d0 Fix a sign extension bug that was unleashed by the previous change.
The total process time was sometimes 2^32 usec too large but that
wasn't a problem before because the time was bogusly truncated mod
2^32.

5fdb832498 Simplify the pseudo-argument removal changes by not optimizing for
the !COMPAT_43 case - use a common function even when there is no
`old' function.  The diffs for this are large because of code motion
to restore the function order to what it was before the pseudo-argument
changes.

Include <sys/sysproto.h> to get correct args structs and prototypes.
The diffs for this are large because the declarations of the args structs
were moved to become comments in the function headers.  The comments may
actually match the automatically generated declarations right now.

Add prototypes.

f668386c04 sio.c:
Fix the tests for being a console by reverting to the ones that
were used before the the RB_SERIAL changes.  RB_SERIAL only needs
to be tested in one place.  The initialization of comconsole was
wrong before the RB_SERIAL changes for the COMCONSOLE case.  This
may have been the cause of the unnecessary changes.

Start eliminating #includes of <i386/i386/cons.h>.  This header is
supposed to be included from <machine> although it should be
completely machine-independent and included from <sys>.

Remove a wrong XXX comment.  `comconsole' is used to test for being
a console and even the tests for deciding the default termios state
are necessary (the semi-reentrant i/o routines don't handle ordinary
device i/o).

cy.c:
Sync with sio.c.  The console tests are present but always fail.

d68a41903e Moved the filesystem read-only check out of the syscalls and into the

725db531b8 Start including <sys/sysproto.h> to get the correct args structs and
prototypes for all syscalls.  The args structs are still declared in
comments as in VOP implementation functions.  I don't like the
duplication for this, but several more layers of changes are required
to get it right.  First we need to catch up with 4.4lite2, which uses
macros to handle struct padding.  Then we need to catch up with NetBSD,
which passes the args correctly (as void *).  Then we need to handle
varargs functions and struct padding better.  I think all the details
can be hidden in machine-generated functions so that the args structs
and verbose macros to reference them don't have to appear in the core
sources.

Add prototypes.

Add bogus casts to hide the evil type puns exposed by the previous
steps.  &uap[1] was used to get at the args after the first.  This
worked because only the first arg in *uap was declared.  This broke
when the machine- genenerated args struct declared all the args
(actually it declares extra args in some cases and depends on the
user stack having some accessible junk after the last arg, not to
mention the user args being on the stack.  It isn't possible to
declare a correct args struct for a varargs syscall).  The msgsys(),
semsys() and shmsys() syscall interfaces are BAD because they
multiplex several syscalls that have different types of args.
There was no reason to duplicate this sysv braindamage but now
we're stuck with it.  NetBSD has reimplemented the syscalls properly
as separate syscalls #220-231.

Declare static functions as static in both their prototype and their
implementation (the latter is optional, and this misfeature was used).

Remove gratuitous #includes.

Continue cleaning up new init stuff.

77d5b24bcb sigset() should have sa_flags cleared to sig is maked before calling
handler (remove SA_NODEFER).

On the other hand, signal() case should set sa_flags to SA_NODEFER as
in previous change.

In addition, added #ifdef'd code for signal() to or in SA_RESETHAND
flag for when that compatability is implemented.

6d875bf526 If we clear the B_CACHE flag because a buffer isn't composed fully of
valid bytes, we must also clear the B_DONE flag.  Some filesystems
depend on this (incl NFS) and is probably the cause of the biodone
error and subsequent crash.  Anyway this change needs to be made.

	Add ps_nodefer field to struct sigacts in signalvar.h.

If flag is set, when the signal is delivered, it is not masked automatically
from receiving the same signal again.

aca1a47cb4 When adding a route fails because there is already a route with the same
(mask,value) in the tree, don't immediately return EEXIST.  Instead, check
to see if the pre-existing route was generated by protcol-cloning.  If so,
then it is OK to simply blow away the old route and re-attempt the insertion.
If not, then fall back to the same error code as before.

3d1f141b23 The ability to administratively change the MTU of an interface presents
a few new wrinkles for MTU discovery which tcp_output() had better
be prepared to handle.  ip_output() is also modified to do something
helpful in this case, since it has already calculated the information
we need.

473fbdbe96 Add a hack to emulator to emulat spx device for local X connections.
This is truly a hack.  The idea is taken from the Linux ibcs2 emulator.

To use this feature, you must use the option,
	options		SPX_HACK
in your config.

Also, in /compat/ibcs2/dev, you must do:

lrwxr-xr-x  1 root  wheel         9 Oct 15 22:20 X0R@ -> /dev/null
lrwxr-xr-x  1 root  wheel         7 Oct 15 22:20 nfsd@ -> socksys
lrwxr-xr-x  1 root  wheel         9 Oct 15 22:20 socksys@ -> /dev/null
crw-rw-rw-  1 root  wheel   41,   1 Oct 15 22:14 spx

Do NOT use old socksys driver as that has been removed.
This hack needs /compat/ibcs2/dev/spx to be any device that does NOT
exist/configured (so the now non-existant spx major/minor works fine).
When an open() is called, the error ENXIO is checked and then the
path is checked.  If spx open detected, then a unix socket is opened
to the hardcoded path "/tmp/.X11-unix/X0".

As the Linux hacker author mentioned, the real way would be to detect
the getmsg/putmsg through /dev/X0R and /dev/spx.  Until this true
solution is implemented (if ever), I think this hack is important
enough to be put into the tree, even though I don't like it dirtying
up my clean code (which is what #ifdef SPX_HACK is for).

30f4c3423d Do a better fake for uname information returned in utssys() call.
Currently, the emulator defaults to returning "FreeBSD" as the system
name, release "3.2", and version "2.0".  Some programs want to make
sure they are on a SYSV 3.2 system and check for 3.X release number.

Use the following defines to override the defaults:
	IBCS2_UNAME_SYSNAME
	IBCS2_UNAME_RELEASE
	IBCS2_UNAME_VERSION
(should be string)
for system name, release, and version, respectively.  This allows
someone to compile the emulator into the kernel so it can pretend
to be a specific system if needed.

287911bd50 Go back to separate tests for configuration mechanism 1 and mechanism 2.
Require the state of the configuration enable bits to be OFF assuming
that the BIOS left them that way, as it should anyway to avoid bad things
to happen.

The tests themselves are copied from the previous release, with the
exception of CONF1_ENABLE_MSK1 having the LSB set. This bit should be
read back as '0', since only DWORD addresses are legal.
