The goal is to make them "user-friendly" :-)

Symorder is enforcing this when the current bsd.kmod.mk is installed.
I've not tested all these, but at least they all compile now.
Reattach them to the makefile.
Note that the change that I made to symorder needs to be compiled and
installed before any LKM's will work - the last version was corrupting
the relocation tables. A "make world" will to this, but if you
manually run a make on the lkm's you'll need to take care of it by
hand.

Set the size before one error return from sysctl_vnode() the same as before

Be more careful in how we deal with SXFRCTL0. Or in the control bits of
interest instead of using mvi. The kernel driver will set the ULTRAEN
bit of SXFRCTL0 if we are using Ultra (20MHz) mode and we don't want to
clobber it.
In sdtr_to_rate divide by two if we are in ultra mode to get the correct
setting since its a 20MHz instead of 10MHz scale.

This is a bulk mport of Mike's IPX/SPX protocol stacks and all the
related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..
Mikes been using it for a year or so
but on 2.0
more changes and stuff will be merged in from other developers now that this is in.

"I screwed the initialization of the burstsize. Right now it will default
to 0 (which can cause corruption problems on high latency PCI buses). It
should be set to 8 longwords to avoid problems with certain PCI chipsets."

at the end of each write for writes of more than 1K.
Fixed handling of residual count for early returns in writes to pty masters.
It was only adjusted in 2 out of 6 cases.
Added prototypes.
TTYHOG = 1024 bytes, 10 cblocks were reserved. This was thought to
provide 10 * CBSIZE = 1080 bytes of buffering, but if the head pointer
is at the end of a cblock, then it only provides 1 + 9 * CBSIZE = 973
bytes of buffering. This caused serious data loss for ptys because the
flow control is deterministic and requires at least TTYHOG bytes of
buffering. For ttys, if input flow control is used then there is
usually enough slop in the high watermark to avoid problems, and if
input flow control isn't used then a limit of 973 is not much different
from a limit of 1024.

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.
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).

Sync with sio.c. The console tests are present but always fail.
filesystem layer, as was done in lite-2. Merged in some other cosmetic
changes while I was at it. Rewrote most of msdosfs_access() to be more
like ufs_access() and to include the FS read-only check.
Obtained from: partially from 4.4BSD-lite2
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.

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.
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 SA_NODEFER define to signal.h
Add ps_nodefer field to struct sigacts in signalvar.h.
Add code to kern_sig.c to handle SA_NODEFER.
If flag is set, when the signal is delivered, it is not masked automatically
from receiving the same signal again.
