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.

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

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.

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!

Update all kernel configs mentioning WSEMUL_* but not already including
WSDISPLAY_COMPAT_USL using the following rules:
- If WSEMUL_ is commented out, add commented out out WSDISPLAY_COMPAT_USL
- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
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.

Now wsconscfg(8) should be able to switch VTs when expected.

Implemented after no objection from tech-kern to the following:

P1003_1B_SEMAPHORE is no longer optional.

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

branches: 1.63.2;

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.

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
should probably be merged into other arches' configs; I'm not going to do
that now though.

Remove the portalfs kernel file system driver. Replace mount_portal(8)

Installation changes:

- 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.

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.

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