Moved description of sio 16650A flag to the sio section and rewrote the
description. It was in the generic console flags section.
Added undocumented options CPU_UPGRADE_HW_CACHE and WLDEBUG.

- Added the psm options PSM_HOOKAPM and PSM_RESETAFTERSUSPEND.
- Added comments on the flag 0x20 for syscons.
- Clarified descriptions on the flags (0x02, 0x04) regarding the cursor
shape in syscons.
fix stopped it being used in all cases, because substitution on unset
variables does not work.
When profiling, put -malign-functions=4 in CFLAGS instead of in PROF.
This fixes the histogram counts for profiling support functions. It
gives bogus but harmless extra alignment for genassym etc.
This eliminates a lot of #ifdef SMP type code. Things like _curproc reside
in a data page that is unique on each cpu, eliminating the expensive macros
like: #define curproc (SMPcurproc[cpunumber()])
There are some unresolved bootstrap and address space sharing issues at
present, but Steve is waiting on this for other work. There is still some
strictly temporary code present that isn't exactly pretty.
This is part of a larger change that has run into some bumps, this part is
standalone so it should be safe. The temporary code goes away when the
full idle cpu support is finished.

NETNATM --> NATM
reported by Bruce Evans.
Bruce also pointed out that NATM is confusing since config(8) defines
NATM as the number of atm pseudo device in "BUILD_DIR/atm.h".
We might change the name in the future but leave it as it is for now.
that I snuck in to our GDB last year. This allows you to debug headless
machines by sharing the console port between the debugger and the system
console. It's not 100% reliabile, but it works well. It's optional
and disabled by default.

profiling frame-pointer-less assembler functions, but gcc doesn't know
about this.)
Added a missing dependency.
Cleaned up trailing backslashes.
Added comment about config's limitations/bugs handling dependencies and
backslashe/newlines.
Finished removing support for isdn drivers.
Remove "setdefs.h" and arrange to generate it automatically at
ELF kernel build time.
"gensetdefs.c" is a utility which scans a set of ELF object files
and outputs a line ``DEFINE_SET(name, length);'' for each linker
set that it finds. When generating an ELF kernel, this is run just
before the final link to generate "setdefs.h".
Remove the init_sets() function from "setdef0.c", and its call from
"machdep.c". Since "gensetdefs.c" calculates the length of each
set, it is no longer necessary in an ELF kernel to count the set
elements at kernel initialization time. Also remove "set_of_sets"
which was used for this purpose.
Link "setdef0" and "setdef1" into the kernel only if building for
ELF. Since init_sets() is no longer used, there is no need to link
them into an a.out kernel.
- merged SMP option SMP_AUTOSTART from LINT
- enabled SMP_AUTOSTART, since it's the desired working mode and it's
reported to work now.

Sigh. The CDIOREADTOCENTRYS did a copyout() of its own, and thus has
been unusable for me for this work. Too bad it didn't simply stuff
the max 100 entries into the struct ioc_read_toc_entry, but relied on
a user supplied data buffer instead. :-( I now had to reinvent the
wheel, and created a CDIOREADTOCENTRY ioctl command that can be used
in a kernel context.
While doing this, i noticed the following bogosities in existing CD-ROM
drivers:
wcd: This driver is likely to be totally bogus when someone tries
two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY)
commands with requesting MSF format, since it apparently
operates on an internal table.
scd: This driver apparently returns just a single TOC entry only for
the CDIOREADTOCENTRYS command.
I have only been able to test the CDIOREADTOCENTRY command with the
cd(4) driver. I hereby request the respective maintainers of the
other CD-ROM drivers to verify my code for their driver. When it
comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will
only consider drivers where i've got a confirmation that it actually
works.

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.
