 1.40  29-Jun-2021  nia Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.
 1.39  04-Apr-2020  jdolecek branches: 1.39.8;
mark nsmb major obsolete
 1.38  29-Jan-2020  maya remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.
 1.37  28-Jan-2019  dholland branches: 1.37.6;
Systematize handling of removed drivers.

- Every driver that was removed and whose number hasn't already been
reused is now listed with a commented-out "obsolete" line.
- The format of these has been systematized. Future format changes can
probably be safely done with a script.
- This does not include a few cases of assignments that only lasted a
couple days, or stuff from before major reorgs. Some of these may
be included nonetheless, because there was a lot of ground to cover
and therefore not a lot of time to dig into history in detail.

Note that the obsolete listings do not mean the major numbers can
never be reused; that's up to portmasters and/or core. It does mean
that they won't be reused by accident, however, which in some cases
(depending on the driver, how widely used it was, its family of device
nodes, their default permissions, etc.) can be quite dangerous.

Note that some of the things now explicitly listed as obsolete are
really ancient history. My scan went back as far as when the majors
files were added. (But not before that.)
 1.36  19-Dec-2018  maxv Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.
 1.35  23-Sep-2018  maxv Remove ISDN from the kernel. It has remained unmaintained for a long time,
is of poor quality, and is now an obstacle to MP-ification. It was removed
ten years ago from FreeBSD for the same reason.

This retires a big user of the mbuf API, and will ease maintenance of the
kernel.
 1.34  26-Mar-2017  martin branches: 1.34.12; 1.34.14;
Assign majors for ld(4)
 1.33  23-Apr-2015  pgoyette branches: 1.33.2; 1.33.4;
Update device dependency information - the sysmon major device now depends on the sysmon module itself, not on the individual components.
 1.32  30-Jun-2011  wiz branches: 1.32.12; 1.32.30;
dependant -> dependent
 1.31  06-Mar-2010  plunky use a MI major number for uhso(4) driver
(requested by mrg)
 1.30  06-Mar-2010  plunky add major device for usho(4) driver
 1.29  12-Nov-2008  ad Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.
 1.28  31-Dec-2007  ad branches: 1.28.6; 1.28.10; 1.28.16; 1.28.18;
Remove systrace. Ok core@.
 1.27  24-Nov-2006  wiz branches: 1.27.28; 1.27.34; 1.27.42;
s/independant/independent/, from Zafer.

 1.25  17-Sep-2005  yamt make VMSWAP optional again.
 1.24  31-Jul-2005  yamt revert "defflag VMSWAP" changes for now.
there seems to be far more people who don't want to edit
their kernel config files than i thought.
 1.23  30-Jul-2005  yamt defflag VMSWAP.
 1.22  13-Jul-2005  kiyohara obsolete fwiso.
 1.21  03-Jun-2005  blymn branches: 1.21.2;
Removed verified exec major, now a MI one.
 1.20  13-Sep-2004  drochner branches: 1.20.10;
add "joy"
 1.19  24-Jul-2004  mrg Hauke Fath's port of the openbsd SUNW,spif driver from PR#26061.
the driver was originally written by Jason L. Wright.

XXX: i haven't tested this on sparc64 at all...
 1.18  10-Dec-2003  jmc Change reference at bottom from sys/dev/majors to sys/conf/majors to match
reality
 1.17  07-Dec-2003  christos add altq
 1.16  10-Oct-2003  jdolecek reassing majors for crypto and pf to use the newly defined MI major
range
 1.15  10-Oct-2003  jdolecek update the comment - the space for machine-dependant majors
is reduced to 0-143
follows discussion on tech-kern
 1.14  05-Oct-2003  jdolecek Add some framework for MI assignment of device majors - add sys/dev/majors
which is automatically included during kernel config, and add comments
to individual machine-dependant majors.* files to assign new MI majors
in MI file.

Range 0-191 is reserved for machine-specific assignments, range
192+ are MI assignments.

Follows recent discussion on tech-kern@
 1.13  22-Aug-2003  itojun create /dev/crypto
 1.12  08-Aug-2003  rafal To make keeping these two in sync easier, add commented-out entries for
device-majors used on the other port to each of the sparc{,64} majors
files.
 1.11  08-Aug-2003  rafal Add major 85 for radio(4).
 1.10  27-Jul-2003  itojun reserve cdev major # for PF. ok'ed by technical-exec

 1.4  04-Oct-2002  elric branches: 1.4.2;
assign majors for raw and cooked cgd's.
 1.3  28-Sep-2002  martin Add entries for various USB character devices.
From Takeshi Nakayama in PR 18450.
 1.2  06-Sep-2002  gehenna branches: 1.2.2;
Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
