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
and because, before enabling it, I'd like to do some other changes.

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

attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

present (commented out if the SYSV* options are commented out).
Fix lib/25897 and lib/25898.

Add (commented out) ALTQ options to all GENERIC-like files

have pf and pflog pseudo-device (commented out).
reviewed by matt, perry, christos

ptm is now mandatory, depends on pty, and can be disabled with -DNO_DEV_PTM

Add pseudo-device ptm on all the generic flavored kernels.

branches: 1.52.2;
Use one 'atabus* at ata?' instead of multiple 'atabus* at FOOide? channel ?'
Use 'atapibus* at atapi?' instead of 'atapibus* at atabus?'

Add atabus.

branches: 1.50.2;
Add pseudo-device ksyms.

Bye Bye UCONSOLE

Make BRIDGE_IPF an option, and document it. Add it (commented) to GENERIC.
Let brconfig tell whether the bridge is using the ipfilter hook, or not.

Added commented out cgd(4)s to GENERIC configs.

add SYSTRACE; approved perry.

Add one space between "#option" and "<tab>IPFILTER_DEFAULT_BLOCK"

Added (commented out) IPFILTER_DEFAULT_BLOCK.

enable USERCONF by default; it's small and extremely useful to have available.

Add options BSDDISKLABEL_EI and options COMPAT_MMEYE_OLDLABEL.

g/c COMPAT_13 - there wasn't any 1.3 release of mmeye. According
to removal log of sys/arch/sh3/sh3/compat_13_machdep.c, COMPAT_13 was trace
of i386 port.

branches: 1.40.2;
Enable "pseudo-device clockctl" in all kernels, except
installation related kernels (INSTALL* and RAMDISK*).
This enables rc.conf(5) $ntpd_chroot to be used "out of the box"

branches: 1.39.2; 1.39.4;
Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size
requirements.

Rename MEMORY_DISK_SIZE (formerly MINIROOTSIZE) to MEMORY_DISK_ROOT_SIZE,
which was suggested by Izumi Tsutsui <tsutsui@ceres.dti.ne.jp> as
being more consistent with what it's controlling...

adapted to new interrupt code and shb changes.

* rename MINIROOTSIZE to MEMORY_DISK_SIZE, so that all md(4) options
are now consistently named
* fold opt_mdsize.h into opt_md.h

The "gif*" tunnelling interface does everything ipip does.
Move usage example from ipip.4 to gif.4
Excise ipip and stitch up the scars.

To determine CPU architecture and product, add cpu_arch and cpu_prduct variables.
these are initialized by sh_cpu_init()@sh3/sh3_machdep.c
(see sh3/include/cputypes.h for detail.)
add "options SH3" for SH3 kernel config file.

add options PIPE_SOCKETPAIR to individual kernel configs
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines

Add new RF_* options for RAIDframe bits that are no longer built by default.

While we're here, enable RAIDframe (and RAID_AUTOCONFIG) by default for
architectures that I'm comfortable can deal with it being on by default.

Also: bump the number of 'raid' devices from 4 to 8, since 4 seems to
be insufficient in practise.

Add PPPoE to all generic kernels that should be able to use it.
XXX TODO: do this for INSTALL kernels too, add sysinst support and make the
XXX needed binaries available on the ramdisk root fs.

Add a blurb to the top of all GENERIC files. This serves three purposes:
- to clarify some terminology
- to clarify the intention of the GENERIC file
- to cross-reference some useful man pages

The bridge(4) pseudo-device no longer requires the port to
__HAVE_GENERIC_SOFT_INTERRUPTS, so add it back to all GENERIC configs.

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\""

Comment out bridge pseudo devices from ports that don't
__HAVE_GENERIC_SOFT_INTERRUPTS. bridge(4) doesn't compile there.

Add bridge pseudo devices to GENERIC configs

branches: 1.24.2;
Standardise TCP_COMPAT_42 as commented out, grouped with other COMPAT options,
and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)

Add System V semaphore resource limits to each GENERIC file that has an
option for System V semaphores. It appears that there are no overrides
in the code and each file has the following added.

options SYSVSEM # System V semaphores
+#options SEMMNI=10 # number of semaphore identifiers
+#options SEMMNS=60 # number of semaphores in system
+#options SEMUME=10 # max number of undo entries per process
+#options SEMMNU=30 # number of undo structures in system
options SYSVSHM # System V shared memory

If anyone thinks that this is incorrect for any of these files, please
correct it.

Note - the i386 port was not forgotten. It was done separately.

wdog* does not compile due to the lack of WDOG_IRQ.

Add pseudo-device vlan

fix shpcic* iomem size from 0x4000000 to 0x1000000

don't specify number of ptys if >= 16 (current default initial number)
pty comments: normalize and g/c what is no longer relevant

move "options PULLDOWN_TEST" into sys/sys/mbuf.h (in #ifdef _KERNEL),
as it is no wthe default setting for everyone.

the reason we still use the name "PULLDOWN_TEST" while it is now default:
kame code sharing.

Moving to a default of 64 PTYs.

add PULLDOWN_TEST for all the platforms.
XXX should be moved to somewhere else when stabilized

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

branches: 1.14.2;
Remove the obsolete config fragments for kernel crypto, because the IPsec
crypto code is now in the kernel source tree.

branches: 1.13.2;
add stf pseudo interface (commented out due to possible security risks)

add commented out option PCI_CONFIG_DUMP whever there's a PCIVERBOSE.

Do the "<space><tab>" thing with the RAID_AUTOCONFIG option.

Defopt 'RAID_AUTOCONFIG'. Adding 'options RAID_AUTOCONFIG' turns on
the component auto-detection and auto-configuration of RAID sets.
Also, add "#options RAID_AUTOCONFIG" to the GENERIC config files.

watchdog timer

remove PMAP_NEW

Add commented out "ident"-command

Add overlay to kernel configs.

bring in content of GENERIC.v6 into GENERIC.
remove GENERIC.v6 file (as it is part of GENERIC now).

"faith" interface is commented out by default as it is not really for
general use.
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}?

Add commented out option SOFTDEP to all GENERIC kernels.

branches: 1.3.2; 1.3.8;
Sync with -current.
XXX root on nfs don't work, though root on wd0 works well.

remove mainbus pseudo floppy drive

Merge in NetBSD/sh3 from cvs.kame.net repository.

Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).

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.

vether: Add to kernel configurations

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

Remove references to BRIDGE_IPF, it is now compiled in by default.

Remove the strip(4) - Starmode Radio IP - pseudo-device driver. It is
long since obsolete.

branches: 1.126.4;
Enable BUFQ_PRIOCSCAN, CARP, Veriexec by default in GENERIC kernel configs.
On ports without a GENERIC kernel config enable in individul files, e.g evbmips.
Omit on:
atari, dreamcast, emips, epoc32, evbppc/VIRTEX*, ia64, luna68x, mvme68k,
mvmeppc, playstation2, riscv, sun2, sun3, x68k, zaurus due to resource
constraints or port infancy.

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

branches: 1.124.2; 1.124.4;
clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

Remove support for VERIFIED_EXEC_FP_RMD160, VERIFIED_EXEC_FP_SHA1, and VERIFIED_EXEC_FP_MD5 options.
These algorithms are either broken or on their way to being broken.

Remove TCP_COMPAT_42 from the config files. Pass 3.

Remove KMEMSTATS.

branches: 1.120.2;
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.

Add "options COMPAT_70" to all kernel configuration files that
already had "options COMPAT_60".
