Add optoion GENERIC.local include to the end of ~all GENERIC configs

This excludes atari, sgimips, evbmips, evbppc, evbsh3, and hpcarm
all of which have somewhat specific kernel config file layouts

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:
- sun2/GENERIC
- dreamcast/GENERIC
Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:
- alpha/GENERIC
- amd64/GENERIC
- evbmips/OCTEON
- i386/GENERIC
- riscv/GENERIC

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.

At this point it is highly unlikely this 1999 device still has users,

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)

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

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.

completely. Only powsw0 is enabled in GENERIC by default.
- prevent chattering in some hardware individuals.
thank you for a report and a test: Yasushi Oshima and Y.Sugahara.

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable

Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently

the conclusion is that scanner software has all moved to using ugen(4)

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)

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.

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

completely. Only powsw0 is enabled in GENERIC by default.
- prevent chattering in some hardware individuals.
thank you for a report and a test: Yasushi Oshima and Y.Sugahara.

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable

IPsec items are commented out as well, though we can enable "options IPSEC"
without export-related issue ("options IPSEC" will enable authentication
portion only). We may need to think about it again.

if you have problem compiling with INET6 on archs I do not have access to,
please contact me.

XXX what to do with arch/arm32/SHARK{,.v6}?

Remove MAPPEDCOPY (somewhat buggy?).

Add commented out option SOFTDEP to all GENERIC kernels.

branches: 1.36.2; 1.36.8;
It's time to be COMPAT_14.

enable PPP_BSDCOMP, PPP_DEFLATE, PPP_FILTER, PFIL_HOOKS, IPFILTER_LOG
on the GENERIC kernels that had them commented out.
XXX: Please note, that not all the kernels have all the options defined!

Remove experimental/buggy options.

Add COMPAT_SVR4 for m68k.

Add missing par0.

branches: 1.31.2;
Enable rnd.

clean up kernel/config files files for machVM lossage.

MACHINE_NONCONTIG -> EXTENDED_MEMORY.
G/c and comment changes.

Merged minoura_x68k_bus_h branch.

MACHINE_NEW_NONCONTIG is no longer optional
remove non-MNN code

Switch x68k port to UVM by default.
Mach VM and even old contig and non-contig codes are still alive.

branches: 1.25.2;
Added options COMPAT_LINUX and EXEC_ELF32 as comments
to GENERIC configuration files.

Add (commented out) 'gre' pseudo device line. Feedback is welcome.
Inspired by Klaus Klein.

Added a (commented out) configuration line for the RAIDframe device driver.

Reorganized the config files based on NetBSD/sparc ones.
Removed unmaintained files.

Deleted unused options EIOMAPSIZE and ITEKANJI.
Removed unmaintained configs.

Switched to MI zs driver.

remove options FIFO; it's now the default

Add commented out "options FFS_EI"

Add COMPAT_13.

add pseudo-device rnd, commented out

* add commented out DDB_HISTORY_SIZE=100 if DDB exists in config file
* fix up use of 'options<SPACE><TAB>'

branches: 1.14.2;
Add options M68060, mha driver.

add a before tab to SCSIVERBOSE

add commented out reference SCSIVERBOSE option

branches: 1.11.4;
remove now obsolete "swap on..." lines.

cleanup use of whitespace

Oops! NFSCLIENT -> NFS

Update for new file system and root spec grammar.

Eliminate obsolete TIMEZONE and DST options.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

branches: 1.6.2;
add EXEC_SCRIPT and EXEC_AOUT

Document COMPAT_M68K4K, but leave it disabled by default.

add COMPAT_12.

fixed kernel couldn't boot from most machines. more generic for x68k.

fd* is need to boot from floppy

branches: 1.1.1;
Initial revision

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:
- sun2/GENERIC
- dreamcast/GENERIC
Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:
- alpha/GENERIC
- amd64/GENERIC
- evbmips/OCTEON
- i386/GENERIC
- riscv/GENERIC

PR kern/29702

UFS/LFS dirhash:
- Enable UFS_DIRHASH if the architecture or kernel model specific config
file can use 128MB of RAM or more.
- Remove experimental tag from UFS_DIRHASH; it's been with RUMP kernel
and by a number of NetBSD developers for years.
- Add LFS_DIRHASH if LFS was enabled.
- Be somewhat consistent with FS options order.

Specify -fno-unwind-tables to shrink binaries.

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: 1.203.4;
add a commented out compat_ossaudio wherever there's compat_linux

requested by mrg

branches: 1.202.2;
vether: Add to kernel configurations

It's only enabled if the kernel enabled bridge AND tap.
Otherwise it's commented out.

Add -fno-omit-frame-pointer to m68k kernels with DDB for backtraces.
-omit-frame-pointer is enabled for -O1 and higher for GCC8 by default.
