Retire "le* at pci?" from the shipped kernel configs:
- If the config had both an le@pci and a pcn, simply remove le@pci
(pcn would match at a higher priority anyway).
- If the config had le@pci enabled, but no pcn, change le@pci to pcn.
- If the config had le@pci commented out, but no pcn, change le@pci
to pcn and leave it commented out.

The pcn driver supports more chips than le@pci and does DMA directly
to/from mbufs rather than memory copies.

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.

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
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

interface to interrupt code for all different OEA ppc arches. The work

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.

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".

branches: 1.143.2;
Add commented out bpfjit options to mips kernels.
While here, add 2 missing RCS ids.

branches: 1.142.4;
G/C PFIL_HOOKS from the kernel configs.

branches: 1.141.2;
remove obsolete networking options

more bogus number removal

the bogus number police

remove confusing numeric locators where they are unused.

Under FAST_IPSEC, IPSEC_ESP is mandatory; GC it.

Retire OSI network stack. OK core@

Add "options COMPAT_60" to all kernel configuration files
that already had "options COMPAT_50".

branches: 1.134.2;
P1003_1B_SEMAPHORE is no longer optional.

branches: 1.133.2;
WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.132.2;

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
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

branches: 1.131.2;
dependant -> dependent

TAB/space cosmetics.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

Merge forward from matt-nb5-mips64.
(XXX generic kernels on raq2 die after interrupts are enabled but gxemul
works fine).

branches: 1.127.2; 1.127.4;
Remove unused count from pseudo-device md.

enable IPFILTER_COMPAT in all kernels that have ipfilter already.
canonicalise several of the ipf option segments in various files
(this mostly means adding commented out IPFILTER_DEFAULT_BLOCK,
or adding commented or uncommented IPFILTER_LOG or IPFILTER_LOOKUP
option statements.)

i built about 20 of these kernels to check, but not all of them.

enable TMPFS in all GENERICs that have MFS enabled.

Remove unused count (invariably "4") from pseudo-device fss.

branches: 1.123.2; 1.123.4;
Remove the portalfs kernel file system driver. Replace mount_portal(8)
with a version based on puffs. User functionality remains the same.

add COMPAT_50 to all the configs with COMPAT_40.

Remove softdep, pass 1. We are focused on improving journalling.

Proposed on tech-kern@.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

branches: 1.119.6;
- fix (commented out) SBLive! driver name; it's emuxki, not sbl
- add commented out audio* at audiobus? line

Enable smbfs, tested by several people on port-cobalt.

branches: 1.117.2;
Add accept filters to GENERIC kernels where they exist.

Add "options WAPBL" to standard GENERIC/INSTALL type configs.

branches: 1.115.4; 1.115.6; 1.115.10;
Add zsc(4) and zstty(4) for Qube 2700.

Comment out some PCIIDE devices which wouldn't be available for a PCI slot.

Enable puc at pci and com at puc, which might be useful Qube2700.

Add options COMPAT_40.

branches: 1.111.2; 1.111.6;
Remove systrace. Ok core@.

branches: 1.110.2; 1.110.8;
Remove System V semaphores and share memory options to set the limits:
SEMMNI, SEMMNS, SEMUME and SHMMAXPGS.

They can be tweaked via sysctl now. Ports that were setting values on
them weren't touched, I only removed the ones that were commented out.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
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.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

branches: 1.108.8; 1.108.10; 1.108.14;
Add pseudo-device agr to all GENERIC kernels where it might make sense
(commented out in some).

branches: 1.107.2; 1.107.8; 1.107.10; 1.107.16; 1.107.18;
Remove options SOSEND_NO_LOAN. Now it's handled in mips/pmap.c.

Remove tmpfs's experimental status. OK'ed by core@.

- Document COMPAT_15 as doing nothing
- Add COMPAT_15 to all the kernel that had COMPAT_14, for the sake of coherency
- Remove the only occurences of #ifdef COMPAT_15 in the tree: for the ARM
ports, COMPAT_15 was always used in conjunction with EXEC_AOUT. Only EXEC_AOUT
matters here.

This address kern/18407

branches: 1.104.2; 1.104.4;
PR/34283: Gene ENonymous: Add IPFILTER_LOOKUP to the default kernel options
Also remove CCITT,NS,NIP

Remove obsolete #options VERIFIED_EXEC, found by grep(1).

Add options SOSEND_NO_LOAN. See the following comment for details:
---
# XXX Disable zero-copy page loaning in sosend() temporarily:
# PV mappings created by sosend_loan() in sys/kern/uipc_socket.c may
# produce virtual cache aliases and it seems to cause TLB MISS panic
# in cache flush code called from bus_dmamap_sync(9) PREWRITE ops
# during heavy TX packet traffic on tlp(4).

Disable SYSTRACE by default on all kernels (discussed with core)

branches: 1.100.2;
Use CPUFLAGS="-march=vr5000 -mabi=32".

Add CARP to GENERIC kernel configs. CARP is not enabled by default.
