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 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

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.

Remove option COMPAT_386BSD_MBRPART from default kernels. NetBSD has
not used partition ID 0x165 for many, many years, and the presence of
this option in INSTALL kernels can cause overwriting of existing FreeBSD
installations when sysinst writes back the disklabel. Those with very,
very old NetBSD installations may find that they must update their fdisk
partition tables to use partition ID 0x169 for their NetBSD partitions.

This seems like the best of a number of lousy choices for dealing with
this problem. Sysinst should perhaps grow code that asks whether an
existing 0x165 partition should be converted.

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

IPv4 PIM support, based on a submission from Pavlin Radoslavov posted on
tech-net@

update the comment for ichlpcib to include SpeedStep.

Implement border color customization in wscons(4), only available for vga(4)
at the moment.

This includes the addition of two new wsdisplay ioctls, WSDISPLAY_{G,S}BORDER,
one to get the actual color and one to set it, respectively. Possible colors
match those defined by ANSI (and listed in wsdisplayvar.h).

It also adds two accessops to the underlying graphics device, getborder and
setborder, which mach their ioctl counterparts.

Two kernel options are added: WSDISPLAY_CUSTOM_BORDER, which enables the
ioctls described above (to customize the border color from userland after
boot), and WSDISPLAY_BORDER_COLOR, which sets the color at boot time.
The former is enabled by default on the GENERIC kernel, but not on INSTALL
(among others). The later is always commented out, leaving the usual black
border as a default.

wsconsctl is modified to allow accessing this value easily. For example,
'wsconsctl -d -w border=blue'.

Implement support to dynamically change wscons console and kernel colors.

Two new ioctls are added to the wsdisplay device, named WSDISPLAY_GMSGATTRS
and WSDISPLAY_SMSGATTRS, used to retrieve the actual values and set them,
respectively (the name, if you are wondering, comes from "message attributes").

A new emulop is added to the underlying display driver (only vga, for now)
which sets the new attribute for the whole screen, without having to clear
it. This is optional, which means that this also works with other drivers
that don't have this new operation.

Five new kernel options have been added, although only documented in
i386 kernels (for now):
- WSDISPLAY_CUSTOM_OUTPUT, which enables the ioctls described above to
change the colors dynamically from userland. This is enabled by default
in the GENERIC kernel (as well as others) but disabled on all INSTALL*
kernels (as this feature is useless there).
- WS_DEFAULT_COLATTR, WS_DEFAULT_MONOATTR, WS_DEFAULT_BG and WS_DEFAULT_FG,
which specify the default colors for the console at boot time. These have
the same meaning as the (already existing) WS_KERNEL_* variables.

wsconsctl is modified to add msg.default.{attrs,bg,fg} and
msg.kernel.{attrs,bg,fg} to the display part, so that colors can be changed
after boot.

Tested on NetBSD/i386 with vga (and vga in mono mode), and on NetBSD/mac68k.
