- 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.
- 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
put_fs_word() to fuword() and suword(). Linux words are 16 bits
but BSD words are 32-bits, at least on vax's. Writing a too-large
word trashed the neighbouring short word.

matter, but similar bogusness in npx.c causes compiling without -O to fail.
Use __volatile in all asms.
Parenthesize macro args.
Change the names of the macros to avoid namespace pollution.
Remove unnecessary "#ifdef __i386__".
Sort #defines.
Add comments.
have got the following:
Back out the changes in the previous revision. Function-like macros
were replaced by compound statements that work in less contexts.
Unoformize idempotency #ifdef.
Restore the simple leap year calculation as a macro and document it so
that it doesn't become complicated again. The simple version works
for all leap years covered by 32-bit time_t's. The complicated version
doesn't work for all leap years covered by 64-bit time_t's since among
other reasons, the solar system is not stable for long enough.
Fix declarations.
Nuke spinwait().
"gcc -Wstrict-prototypes" doesn't emit warnings about them.
Write each min/max functions on a single line so that the similarity and
triviality of the functions is more obvious.
Put the quad min/max functions in the correct place (aphabetical order).
The u_quad min/max functions are missing. Only 3 or 4 of the min/max
functions are actually used. sys/socketvar.h ``should use "lmin" but
it doesn't exist now''. lmin does exist now, but isn't used. Since we
depend on gcc for `inline', perhaps we should depend on it for __typeof
and function-expressions and use only macros min() and max() that work
for any types (I'm not sure how to handle mixed types).
actually used.
Remove "#ifdef __GNUC__" around some __dead* declarations. __dead* is
harmless if __GNUC__ is not defined.
Uniformize idempotency #ifdef.
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.
