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.

Adjust _all_ cinclude of *.local files

- Ensure always at end
- Use tab rather than spaces
- Add consistent comment
"Pull in optional local configuration - always at end"

The only functional change is that a local file which tried to
override an existing setting (eg with "no foo") would have failed
in some cases before, but now will work

Remove uyap, USB YAP phone firmware loader.

And the associated ezload EZ-USB code, which is only used by uyap.
It could theoretically be used by other drivers, but none of them are
in tree.

I suspect that this device isn't in use, as phone technology has improved
a lot since 2001 when uyap(4) was added to the tree.

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.

Remove FDDI support.

Remove Token Ring support.

Remove HIPPI support and the esh(4) driver that uses it. There have not
been any users of HIPPI for some time, and it is unlikely to be resurrected.

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

branches: 1.49.6;
Add ure(4) to kernel config files. Also add PHY drivers where necessary.

Remove the satlink driver. It was disabled everywhere, had no man page and
no use either. Spotted by thorpej in PR/21345, ok christos.

Remove references to "lmc" in the kernel configurations.

Retire the 'midway' driver. Discussed on tech-net@ recently and also three
years ago, part of removing the network ATM code.

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

Unreference IPF/PF from the x86 config files (amd64, i386, xen), and enable
NPF instead when wanted.

Revive commented out DISKLABEL_EI option to kernel configuration files
that contain FFS_EI option.

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 vm86 on i386. It is bug-friendly, and there is no point
in having kernel support for this: the instruction set of the CPU is small,
and it can easily be emulated in userland entirely. There are also several
assumptions in the code that are not respected, and the slightest confusion
in the trap frame can lead to ring0 exploits.

vm86 has received zero maintenance. As far as I can tell, it was added
20 years ago in order to make doscmd work. But doscmd has not been
maintained either, and was removed from pkgsrc in 2011. dosbox can be used
instead: it does not require kernel support, and will produce better
results than our flimsy implementation.

Pass 1. (many pieces still in the tree)

Remove compat_ibcs2 from i386. After a discussion on port-vax, it turns
out that compat_ibcs2 does not implement the iBCS2 standard - which is
x86-specific - but rather SVR3. Our real iBCS2 implementation was a
mixture of compat_ibcs2 and compat_svr4, and was only partial. Keeping
support for this in i386 is totally irrelevant today. I also asked on
port-i386 but didn't wait long.

The main issue is that compat_ibcs2 should have been called compat_svr3.
But CVS does not support renaming files, and moving things around is both
painful and tiring, even more so when no one seems to be interested in
doing this work or in the feature at all. For now compat_ibcs2 is available
on Vax and will stay, until someone (not me) cleans it up.

Remove TCP_COMPAT_42 from the config files. Pass 3.

Remove svr4 from the config files.

PCPPISPEAKER

Add a synthesized pc beeper and keyboard bell for platforms with an audio
device.

* Split sys/kern/sys_process.c into three parts:
1 - ptrace(2) syscall for native emulation
2 - common ptrace(2) syscall code (shared with compat_netbsd32)
3 - support routines that are shared with PROCFS and/or KTRACE

* Add module glue for #1 and #2. Both modules will be built-in to the
kernel if "options PTRACE" is included in the config file (this is
the default, defined in sys/conf/std).

* Mark the ptrace(2) syscall as modular in syscalls.master (generated
files will be committed shortly).

* Conditionalize all remaining portions of PTRACE code on a new kernel
option PTRACE_HOOKS.

XXX Instead of PROCFS depending on 'options PTRACE', we should probably
just add a procfs attribute to the sys/kern/sys_process.c file's
entry in files.kern, and add PROCFS to the "#if defineds" for
process_domem(). It's really confusing to have two different ways
of requiring this file.

branches: 1.29.2;
Remove KMEMSTATS. Normally it's ok now.

Add `pseudo-device ksyms' where `options DDB' is used, because
config(1)/config(5) can't handle module dependency correctly at this
moment.

(This is another proof that shared file definition (`file xxx.c a|b')
is a bad idea.)

branches: 1.27.2;
Install agp_* drivers where pchb(4) is installed except INSTALL_FLOPPY.

XXX
Config around agp(4) is done in quite wrong direction.
"pchb <- (agpbus) <- agp <- agp_*"
should be:
"pchb <- (pcibus) <- agp_* <- (agpbus) <- agp"

Add missing COMPAT_{50,60,70} lines, commented out or not as per the
COMPAT_40 line.

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.

Remove support for 'external' floating point units and the MS-DOS
compatible method of handling floating point exceptions.
Make kernel support for teh fpu non-optional (486SX should still work).
Only 386 cpus support external fpu, and i386 support was removed years ago.
This means that the npx code no longer uses port 0xf0 or interupt 13.
All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c
is now mandatory for all i386 kernels.
I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu()
to match the very similar amd64 functions.
The fpu of the boot cpu is now initialised by a direct call from
cpu_configure(), this enables FP emulation for a 486SX.
(for amd64 the cr0 values are set in locore.S and similar).
This fixes a long-standing bug in linux_setregs() - which did not
save the fpu regsiters if they were active.
I've test booted a single cpu i386 kernel (using anita).
amd64 builds - none of teh changes should affect it.
The i386 XEN kernels build, but I'm not sure where they set cr0, and
it might have got lost!

The rnd pseudo-device is not really optional, because it is in the same

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.

Merged by yours truly as the set of configs has changed quite a bit since
the PR was filed in 2003, and I may have missed some stuff. These changes

For PR kern/38537:

- Make MULTIPROCESSOR mandatory on i386.

Installation changes:

- Update installation section of release notes to match reality.
- Rename INSTALL to INSTALL_FLOPPY, retire INSTALL_LARGE.
- Build INSTALL kernel from GENERIC, like on amd64.
- Update boot menu to allow disabling ACPI and/or SMP.
- Remove GENERIC.NOACPI from the installed kernel list.
- TODO: install default boot.cfg in etc.tgz.
- TODO: possibly enable PCI fixup stuff at runtime if ACPI is disabled.

Build changes:

- No longer build ALL, it's for verification, is slow to build and the
build process is already crippled by the number of kernels built.
- No longer build GENERIC.NOACPI.
