5b976b6d8d Fixed problems with kernel config file overrides of sysv semaphore
parameters.  Prior to this fix a kernel config override would effect
only some of the kernel files, resulting in panics.

9b703b1455 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

4c8218a5c7 Move the "retval" (3rd) parameter from all syscall functions and put
it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft
from the sources.

I have not removed the /*ARGSUSED*/, they will require some looking at.

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

2f3f635ee8 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.

Submitted by:	terry (terry lambert)
This is  a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.
