This means we can untangle certain header files.
options.i386 has a placeholder until it has a real member so we can avoid
having to teach config about it just yet.

There are various options documented in i386/conf/LINT, there is more to
come over the next few days.
The kernel should run pretty much "as before" without the options to
activate SMP mode.
There are a handful of known "loose ends" that need to be fixed, but
have been put off since the SMP kernel is in a moderately good condition
at the moment.
This commit is the result of the tinkering and testing over the last 14
months by many people. A special thanks to Steve Passe for implementing
the APIC code!
have successfully built, booted, and run a number of different ELF
kernel configurations, including GENERIC. LINT also builds and
links cleanly, though I have not tried to boot it.
The impact on developers is virtually nil, except for two things.
All linker sets that might possibly be present in the kernel must be
listed in "sys/i386/i386/setdefs.h". And all C symbols that are
also referenced from assembly language code must be listed in
"sys/i386/include/asnames.h". It so happens that failure to do
these things will have no impact on the a.out kernel. But it will
break the build of the ELF kernel.
The ELF bootloader works, but it is not ready to commit quite yet.

Added obsolete option GATEWAY so that kern_opt.c gets tested.
Added undocumented options LOCKF_DEBUG and SIMPLELOCK_DEBUG so
that these options get tested. The addition of LOCKF_DEBUG shows
that all of kern/kern_lockf.c shouldn't have been moved from ufs.
The debugging parts are very fs-dependent.
probing anytime soon, make EISA_SLOTS a fully supported option. It's
required for the HP NetServer LC series machines.
Next stop: make dset(8) aware of it as well.
become impractical to distinguish versions using "real" release dates, so
might as well make it correspond to real version number (-current is
on the 3.0 branch) so at least the feature increments are guaranteed to
be linear.
Silently approved by: current list
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.
The system boots and can mount UFS filesystems.
Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.
