2. New detection code so we know what boot code called us.
3. Remove old DISKLESS support code and halt if we are called by that boot
code as it will NOT work with the new nfs_diskless structure.
This is really in preperation for new boot code and new diskless support.

never used LISP to any extent). So I compiled the kernel with -Wall and

and added a couple of declarations here and there. Having a lap-top is

Back out the changes in the previous revision. Function-like macros

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().
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.
Removed inb function since it's more correctly in pio.h
Copied write_eflags and read_eflags over from npx.c
(Some changes to the macros suggested by Bruce were not made at this
time since his suggestions probably apply to all the macros and
these inlined/macro definitions need a lot of cleaning up at some
point in the future.)

Fix from Bruce Evans. There were missing sets of parantheses:
1. The checks for the standard data selectors were botched, so %ss == 0
and probably %cs == 0 were allowed. A fix is enclosed. The checks
for the standard selectors could be omitted without losing anything
since the standard selectors pass the valid_ldt_sel() tests.

is only supposed to give definitions suitable for the kernel. The
current definitions for the kernel almost worked but are missing
the ".type" declarations. This caused the linker to print warnings
