Revive commented out DISKLABEL_EI option to kernel configuration files

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)

Pff, I forgot to revert my change in these files. I committed only the
GENERIC files, and the message was:

Revert my changes, and re-enable COMPAT_NOMID, COMPAT_09 and COMPAT_43.
Several compat options happen to be dependent on the compat_43_* functions,
the availability of which is (wrongfully) controlled with COMPAT_43. Same
for COMPAT_09.

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.

Disable all the compat options until COMPAT_10. NetBSD 1.0 was released on

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.

it might have got lost!

Change GENERIC, GENERIC.MP, GENERIC.MPACPI, GENERIC_LAPTOP, INSTALL,
INSTALL.MP, INSTALL_LAPTOP, and DISKLESS kernels so that they are
smaller and faster by removing support for actual i386 CPUs (which
lack write protection in supervisor mode, which requires a costly
workaround) and math coprocessor emulation. Coprocessor emulation
is retained in the LAPTOP kernels, but not in the others. Where
it is known that a configuration cannot be run with particular CPUs
(i486 in *MP kernels) remove that support as well. Compile all
kernels with appropriate architecture and tuning flags (reduces
size, makes things faster). Those requiring support for machines
with i386 CPU or lacking coprocessor can use the *SMALL or *TINY
kernels.

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.

OK'ed by my project mentor, William Studenmund (wrstuden@).

Rework the configuration scheme for PCI fixups:

* bus enumeration fixups are not PCIBIOS-specific, interrupt fixups are done
by both PCIBIOS and ACPI. The redundancy is very redundant. Therefore,
rename PCIBIOS_*_FIXUP to PCI_*_FIXUP, use PCI_INTR_FIXUP in place of
ACPI_PCI_FIXUP, and change code refences to match.

* move the fixup defines from opt_pcibios.h to opt_pcifixup.h to reflect
the above.

* fix up the PCI bus numbering in mainbus_attach(), right after we detect the
configuration mode. This probably renders the fixup in pcibios.c
redundant -- but it should be harmless.

These changes make cardbus work in ACPI-only machines, when PCI_BUS_FIXUP
and PCI_INTR_FIXUP are defined.
