93e010b0fd Fixed bug in hardclock() that caused adjtime() to fail when given 
a negative offset.  This would be seen in xntpd as a rash of
``Previous time adjustment didn't complete'' messages on startup.

3810319894 Moved the "relookup" routine into vfs_lookup.c from ufs/ufs/ufs_vnops.c. 
Several FS's use this, so it doesn't belong in ufs.  (unionfs, msdosfs and ufs)

bb56ec4a05 While in the real world, I had a bad case of being swapped out for a lot of 
cycles.  While waiting there I added a lot of the extra ()'s I have, (I have
never used LISP to any extent).  So I compiled the kernel with -Wall and
shut up a lot of "suggest you add ()'s", removed a bunch of unused var's
and added a couple of declarations here and there.  Having a lap-top is
highly recommended.  My kernel still runs, yell at me if you kernel breaks.

c9b1d6048d More loadable VFS changes: 
- Make a number of filesystems work again when they are statically compiled
  (blush)

- FIFOs are no longer optional; ``options FIFO'' removed from distributed
  config files.

67bfdf835b Fix a few niggling little bugs: 
- set args->lkm_offset correctly so that VFS modules can be unloaded
- initialize _fs_vfsops.vfc_refcount correctly so that VFS modules can
  be unloaded
- include kernel.h in a few placves to get the correct definition of DATA_SET

0b53fbe8da Don't use SIG_DFL or SIG_IGN for case label expressions. ANSI requires 
such expressions to have integral type.  "gcc -ansi -pedantic -W..."

3f31c649d1 Redo Kernel NTP PLL support, kernel side. 
This code is mostly taken from the 1.1 port (which was in turn taken from
Dave Mills's kern.tar.Z example).  A few significant differences:

1) ntp_gettime() is now a MIB variable rather than a system call.  A few
fiddles are done in libc to make it behave the same.

2) mono_time does not participate in the PLL adjustments.

3) A new interface has been defined (in <machine/clock.h>) for doing
possibly machine-dependent things around the time of the clock update.
This is used in Pentium kernels to disable interrupts, set `time', and
reset the CPU cycle counter as quickly as possible to avoid jitter in
microtime().  Measurements show an apparent resolution of a bit more than
8.14usec, which is reasonable given system-call overhead.

f7d6afc696 Be more careful about dereferencing curproc, p_vmspace, and curpcb, 
otherwise the machine will overflow the stack in a recursive fault loop
(causing the machine to spontaneously reboot because of the stack fault
that ultimately happens).

Submitted by:	Inspired by Bruce Evans, but this change is different
		than what he suggested.

fe7bb84c74 Remove <machine/eflags.h> and all dependencies on it. eflags.h is just 
the Mach/i386 version of the BSD/vax(?) <machine/psl.h>.  The Mach
version has slightly better names for many macros but is now out of
date and little used.  It was originally used even less (for spelling
PSL_T as EFL_TF in <machine/db_machdep.h>).
