NSLU2: Remove workaround for now-fixed PR toolchain/57146

Relocate FFS_NO_SNAPSHOT to where it should be...

Sprinkle FFS_NO_SNAPSHOT and -fno-unwind-tables to reduce
memory footprint.

Build NSLU2 kernel with NOCTF="yes" as workaround for
PR toolchain/57146, which I'm working on :).

Now kernel image fits within its reserved VA range again.

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.

PMAP_DEBUG has been deleted on arm

Add ure(4) to kernel config files. Also add PHY drivers where necessary.

remove the 'wd* at umass?' for the non-standardized and rare (extinct?)
In-System Design ATA protocol over Bulk-Only devices from most kernels,
leave only in i386/amd64 ALL; it's unmaintained and likely currently broken,
lack of test hardware makes it impossible to support

Add (commented out) mue(4) to where appropriate.
Also add MII/PHY drivers for USB NICs if missing.

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).

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

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.

ALL on amd64 and i386.

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".

Add COMPAT_NETBSD32 to more kernels (we have too many)

Retire OSI network stack. OK core@

Add "options COMPAT_60" to all kernel configuration files

Add PUFFS, putter and fss.

Rename RT2500USB driver to ural(4) as it was originally in OpenBSD,
as ural(4) and ral(4) do not actually share any code.

Enable ural(4) in hpcarm WZERO3 kernel too, as it will now build.

Fixes PR#43520.

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.

Increase SYMTAB_SPACE to fix compilation of these kernels.

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.

initial limit as 1/4 of the physical memory. Ensure the limit is at

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.

A port of NetBSD to the Linksys NSLU2 (a.k.a. "Slug").

The NSLU2 (Network Storage Link for USB 2.0 Disk Drives) is a small, *cheap*
NAS device consisting of an Intel IXP420 (Xscale) CPU, a 10/100mbit Ethernet
port, and two USB 2.0 ports. It has 32MB of SDRAM and 8MB of Flash memory,
and runs RedBoot/Linux out of the box. Now it can also run NetBSD.
