2. The kernel now does a frame setup on entry so it ``looks'' like a
real function call. This will be needed by future boot code and
debuggers.
3. Clean up stack offsets to all be in decimal and use %ebp when copying
parameters in from the boot code.
4. Implement version 1 of the uniform boot code passing mechanism with
support for kernelname passing and nfs_diskless structure passing.
5. Document the 3 different ways the kernel is called depending on what code
is calling it.
must #define NFS before including <sys/mount.h> to pick up some of
the definitions needed for struct diskless. Be sure to undef it after this
so you do not effect other code.
This is kinda sick, but it does the job. Problem found by davidg.
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.

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.
