option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem

dhcp/bootp is much easier to setup and manage and is easier to debug

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)

Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add

by default to disable it by simply removing/commentting this line.

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.

Driver for the Sun ZX/Leo framebuffer. This would be called leo, but the
amiga port already has a driver by that name.

Enable "pseudo-device clockctl" in all kernels, except
installation related kernels (INSTALL* and RAMDISK*).

branches: 1.134.2; 1.134.4;
- Enable NFS_BOOT_DHCP (as well as the existing NFS_BOOT_BOOTPARAM).
DHCP/Bootp is tried before bootparams in the MI nfs mountroot code.
- Change the order in boot.net from "bootparams then bootp" to
"bootp then bootparams", to be consistent with the MI nfs mountroot code.

(Consistency with other NetBSD ports is good, and things still work
for sites that run bootparams but not dhcp/bootp, although I'd argue that
dhcp/bootp is much easier to setup and manage and is easier to debug
than our rpc.bootparamd...)

Per discussion with Paul Kranenburg and Matt Green.

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.

Update description for icsphy.

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

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

+#options SEMMNS=60 # number of semaphores in system
+#options SEMUME=10 # max number of undo entries per process

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.

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.

crank memory disk from 1360 blocks to 1376 blocks

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

Ensure all INSTALL config files consistantly include PIPE_SOCKETPAIR,
MALLOC_NOINLINE, and VNODE_OP_NOINLINE. The exceptions are when they
include another config files that already defines the options, or if
they are for an embedded board, just define a few extra options, and
do not already define PIPE_SOCKETPAIR.

- Enable NFS_BOOT_DHCP (as well as the existing NFS_BOOT_BOOTPARAM).
DHCP/Bootp is tried before bootparams in the MI nfs mountroot code.
- Change the order in boot.net from "bootparams then bootp" to
"bootp then bootparams", to be consistent with the MI nfs mountroot code.

(Consistency with other NetBSD ports is good, and things still work
for sites that run bootparams but not dhcp/bootp, although I'd argue that
dhcp/bootp is much easier to setup and manage and is easier to debug
than our rpc.bootparamd...)

Per discussion with Paul Kranenburg and Matt Green.

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

Rename MEMORY_DISK_SIZE (formerly MINIROOTSIZE) to MEMORY_DISK_ROOT_SIZE,

(Consistency with other NetBSD ports is good, and things still work
for sites that run bootparams but not dhcp/bootp, although I'd argue that
dhcp/bootp is much easier to setup and manage and is easier to debug
than our rpc.bootparamd...)
