Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART

as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options

Add tap(4) support to a random^Wcarefully chosen set of kernel configs.

Add commented out pf and pflog pseudo-devices.

Add INSTALL and GENERIC kernel configuration wrappers for IP12 family.

Note that devices are defined in the IP2x configuration file; the IP12 is
99.5% the same as the IP20/22/24. Indeed, the only reason to have a separate
config file for IP12 is to sort out the MIPS1/MIPS3 locore bits.

To that end, the wrappers include the IP2x GENERIC config, undefine a few
directives, and define the appropriate bits for IP12.

Add COMPAT_BSDPTY to the rest of the config files.

Move the ECOFF definition from the INSTALL kernel to the GENERIC kernel --
it's possible that someone might want to run an IP20 diskless.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Update all kernel configs mentioning WSEMUL_* but not already including

- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL

Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.

Now wsconscfg(8) should be able to switch VTs when expected.

Implemented after no objection from tech-kern to the following:

P1003_1B_SEMAPHORE is no longer optional.

WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.90.2;

The rnd pseudo-device is not really optional, because it is in the same

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA

interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Due to space limitations, we can't embed a three-meg ramdisk installation image
into an IP12 kernel.

Remove; installation procedure will have to be GENERIC kernel using sysinst
from a NFS filesystem.

Add INSTALL and GENERIC kernel configuration wrappers for IP12 family.

Note that devices are defined in the IP2x configuration file; the IP12 is
99.5% the same as the IP20/22/24. Indeed, the only reason to have a separate
config file for IP12 is to sort out the MIPS1/MIPS3 locore bits.

To that end, the wrappers include the IP2x GENERIC config, undefine a few
directives, and define the appropriate bits for IP12.

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

Completely remove IP2X and IP32, which renders opt_machtype.h obsolete.

Attach int0 at mainbus (precedent being the ip32 CRIME device, which handled
interrupts and timer calibration yet is also attached at mainbus).

Introduce the INDY_R4600_CACHE config option, which more accurately describes
the code enabled by this option.

This renders #ifdef IPxx completely obsolete, thus we theoretically can unify
the GENERIC files if a workable load address relocation scheme can be found.

Following the example of the hpc/, gio/, and ioc/ directories, move the
mace devices to their own mace/ directory. Alter conf/files.sgimips to
reflect this change in a sane manner (i.e., pull in dev/files.dev and
mace/files.mace when appropriate).

At the same time, allow crime_intr_establish() to fall through to
mace_intr_establish(). mace devices now call cpu_intr_establish().

ip2x.c and ip32.c are no more.

Add pic attached at mainbus (for IP12).

Part two in the Great Renaming. ip22.c becomes ip2x.c, and all generic ip2x
routines become ip2x_*.

Add ioc driver to IP2x config file, pull in ioc/files.ioc as well. Note that
IP2x now has blinkenlitzen.

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.

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.

branches: 1.33.8;
mark nsmb major obsolete

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.

branches: 1.31.6;
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.)

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.

branches: 1.1.2;
file majors.sgimips was initially added on branch gehenna-devsw.

Pull in Atheros HAL.

branches: 1.17.78; 1.17.86; 1.17.92;
merge ktrace-lwp.

include "conf/std".

branches: 1.15.16;
Remove historic remnant that treated the O2 load address as the
sgimips standard. Define it in the respective config file.

add "makeoptions MACHINE_ARCH=..." in std.* for mips ports
where it is constant (to ease cross-building).

branches: 1.13.6;
Remove the explicit `makeoptions MACHINE_ARCH="mipse{b,l}"' for kernel
builds and use the endianness of the toolchain being used to determine
the endianness of the kernel.

Change the kernel load address offset from 512K to 420K, the Irix
convention for debugging kernels.

Move the kernel forward in memory, starting it 512K in from the
bottom of RAM. The bootloader is now loaded 2K in from the bottom
of RAM, so we need to make space for it.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

Remove driver options that don't belong in std.sgimips.

branches: 1.8.4;
For MIPS kernel Makefiles, don't set ENDIAN in std.${MACHINE}. Instead,
explicitly set MACHINE_ARCH to the appropriate thing. Makefile.mips will
then set all of the internal variables it needs to accordingly.

branches: 1.7.2;
Delete __NO_SOFT_SERIAL_INTERRUPT.

branches: 1.6.2;
Revert back to a machinearch (really cputype) of mips. Put ENDIAN back.

Change arch from mips to mipsel/mipseb as appropriate. Nuke the ENDIAN
makeoption. Key off MACHINE_ARCH for adding -EB/-EL to CFLAGS/AFLAGS/LD/
LINKFLAGS.

Start using a Makefile.mips. Use a combination of makeoptions and
Makefile.sgimips.inc which has sgimips specific stuff.

branches: 1.3.2;
Update for counter interrupt PSL change.

Remove prefix construction for softdeps. Add SOFTDEP option to GENERIC.

branches: 1.1.2; 1.1.4;
Initial commit.

Merge forward matt-nb5-mips64
Adapt to new interrupt/spl framework
Deal with arcbios calls being O32 and kernels being N32/N64.
Need to save/restore T8 across arcbios calls.
