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.

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.

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.

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.

AHC_FORCE_PIO - This forces the driver to use PIO even on systems that

- use a more accurate and more efficient method of compensating for
overheads. The old method counted too much time against leaf
functions.
- normally use the Pentium timestamp counter if available.
On Pentiums, the times are now accurate to within a couple of cpu
clock cycles per function call in the (unlikely) event that there
are no cache misses in or caused by the profiling code.
- optionally use an arbitrary Pentium event counter if available.
- optionally regress to using the i8254 counter.
- scaled the i8254 counter by a factor of 128. Now the i8254 counters
overflow slightly faster than the TSC counters for a 150MHz Pentium :-)
(after about 16 seconds). This is to avoid fractional overheads.

First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now. Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later. This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted. Now we generate the symbol file in
release.8.
Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two
effects:
1. Userconfig is always entered, rather than only after a -c
(don't scream yet, it's not as bad as it sounds).
2. Userconfig reads a message string which can optionally be
written just past the boot blocks. This string "preloads"
the userconfig input buffer and is parsed as user input.
If the first command is not "USERCONFIG", userconfig will
treat this as an implied "quit" (which is why you don't need
to scream - you never even know you went through userconfig
and back out again if you don't specifically ask for it),
otherwise it will read and execute the following commands
until a "quit" is seen or the end is reached, in which case
the normal userconfig command prompt will then be presented.
How to create your own startup sequences, using any boot.flp image

USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO
Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched. The default
boot.flp startup sequence is now, in fact, this:
USERCONFIG
intro
visual
(Since visual never returns, we don't need a following "quit").

for headers in the compile directory work unsurprisingly. Without
-I-, the search for "foo.h" begins in the directory of the file
that includes it, and the compile directory is only searched because
`-I.' is in ${INCLUDES}.
Removed -I$S/sys from ${INCLUDES}. It was once necessary to find
things like "param.h" in $S/sys. Now <sys/param.h> is found in $S.

This file should be sorted both alphabetically and on the module

If you define this, it means your keyboard is actually probable using the
brain-dammaged probe routine in syscons, and if the keyboard is NOT found,
then you don't want syscons to activate itself further.
This makes life sane for those of us who use serial consoles most of the
time and want "the right thing" to happen when we plug a keyboard in.
