PR/57889: Ricardo Branco: ext2fs does not have user immutable and append
file flags, only system ones. Restrict those to the superuser. Before
the behavior was controlled by EXT2FS_SYSTEM_FLAGS. Make that behavior the
default.

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.

Enable NFS_BOOT_UDP; on-board NIC seems to be too slow for overhead due to
NFS over TCP. Some scores of pkgsrc/benchmarks/bonnie improve nearly x2.

Identify oneself as ``Explora 450'' instead of 451.

There are models numbered 450 to 454. The differences b/w them are
shapes of ethernet and audio connectors. Base model number 450 is
displayed for (probably) all models by firmware.

Add tmpfs.

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 'file-system SMBFS' and 'pseudo-device nsmb' from all kernel configs
to prepare for their eventual removal

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

branches: 1.64.4;
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).

Alternate buffer queue strategies no longer considered experimental, update
description.

Discussed on tech-kern
http://mail-index.netbsd.org/tech-kern/2018/01/21/msg023002.html

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 TCP_COMPAT_42 from the config files. Pass 3.

branches: 1.59.10;
Remove KMEMSTATS.

branches: 1.58.2;
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.

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

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

LLVM builds have a slightly larger symbol table, so bump the space.

G/C PFIL_HOOKS from the kernel configs.

branches: 1.53.2;
remove obsolete networking options

the bogus number police

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: 1.48.2;
Adjust the WSDISPLAY_COMPAT_USL comment to mention wsconscfg, to at least
give a hint that its not just for third party compat. No functional change.

branches: 1.47.2;
WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

Bump SYMTAB_SPACE.

branches: 1.45.2;

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: 1.44.4;
Bump SYMTAB_SPACE so that the contents fits again.

Bump SYMTAB_SPACE.

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

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

Remove SHMMAXPGS from all kernel configs. Dynamically compute the
initial limit as 1/4 of the physical memory. Ensure the limit is at
least 1024 pages, the old default on most platforms.

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.

- 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.
