5a9714de76 This mega-commit brings the following:
. It makes cd9660 root f/s working again.
. It makes CD9660 a new-style option.
. It adds support to mount an ISO9660 multi-session CD-ROM as the root
  filesystem (the last session actually, but that's what is expected
  behaviour).

Sigh.  The CDIOREADTOCENTRYS did a copyout() of its own, and thus has
been unusable for me for this work.  Too bad it didn't simply stuff
the max 100 entries into the struct ioc_read_toc_entry, but relied on
a user supplied data buffer instead. :-(  I now had to reinvent the
wheel, and created a CDIOREADTOCENTRY ioctl command that can be used
in a kernel context.

While doing this, i noticed the following bogosities in existing CD-ROM
drivers:

wcd:	This driver is likely to be totally bogus when someone tries
	two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY)
	commands with requesting MSF format, since it apparently
	operates on an internal table.

scd:	This driver apparently returns just a single TOC entry only for
	the CDIOREADTOCENTRYS command.

I have only been able to test the CDIOREADTOCENTRY command with the
cd(4) driver.  I hereby request the respective maintainers of the
other CD-ROM drivers to verify my code for their driver.  When it
comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will
only consider drivers where i've got a confirmation that it actually
works.

d75a8fdbb1 Addresses the following two problems.
1) i586_bcopy() problem

There have been a number of reports that the syscons doesn't work
properly if i586_bcopy() is enabled.

The problem prevented users from installing 2.2(.1)-RELEASE.  The
symptom is that the system looks frozen during device probe or just
before the main installation menu.  The workaround was to specify the
flag 0x01 to the npx device so that i586_bcopy() is disabled.

The patch forces the syscons to call generic_bcopy() when copying
to/from the video memory, even if CPU is Pentium and i586_bcopy() is
enabled. i586_bcopy() is still called for copy operations between
non-video memory regions.

PR: kern/2277, kern/3066, kern/3107, kern/3134

2) video mode parameter table problem

The syscons reads and uses the video mode parameter table provided by
the VGA BIOS to set VGA registers when changing video mode and
modifying font data. It appears that in some VGA BIOSes the table is
not ordered as the syscons expects, and this leads to screen
corruption.

The problem prevented users from installing 2.2(.1)-RELEASE. The
symptom is the corrupt screen or strange vertical lines soon after the
kernel is loaded into memory (just after the kernel decompression).

The patch performs simplistic test and if it fails, set video_mode_ptr
to NULL so that the video mode switching won't happen.

This is an interim kludge. There should be a better way to deal with
the problem.

The SMP source was merged into 3.0-current last nite and this broke

Should make things work for non-SMP case.

People making SMP kernels will need to edit i386/isa/isa_device.h, re-enabling
'#include "opt_smp.h"'.  People making SMP worlds will have to punt for now...
I'm thinking about the real solution, but for now the goal is to NOT break

477a642cee Man the liferafts! Here comes the long awaited SMP -> -current merge!
There are various options documented in i386/conf/LINT, there is more to
come over the next few days.

The kernel should run pretty much "as before" without the options to
activate SMP mode.

There are a handful of known "loose ends" that need to be fixed, but
have been put off since the SMP kernel is in a moderately good condition
at the moment.

This commit is the result of the tinkering and testing over the last 14
months by many people.  A special thanks to Steve Passe for implementing
the APIC code!

9081eec1fb Make the necessary changes so that an ELF kernel can be built. I
have successfully built, booted, and run a number of different ELF
kernel configurations, including GENERIC.  LINT also builds and
links cleanly, though I have not tried to boot it.

The impact on developers is virtually nil, except for two things.
All linker sets that might possibly be present in the kernel must be
listed in "sys/i386/i386/setdefs.h".  And all C symbols that are
also referenced from assembly language code must be listed in
"sys/i386/include/asnames.h".  It so happens that failure to do
these things will have no impact on the a.out kernel.  But it will
break the build of the ELF kernel.

The ELF bootloader works, but it is not ready to commit quite yet.

Don't cast NULL in calls to timeout functions.  pcvt is fully prototyped

Timeout functions take args of type `void *', so use magic numbers of
type `void *' for UPDATE_* to reduce the danger of wrong conversions.

03dcce7f3d Incorporate kludge/fix from `syscons' ver 1.207 and 1.209.
1) Dell Latitude XPi
This laptop has a strange, IMHO broken :-), keyboard controller which
wouldn't disable the keyboard interrupt. The kludge is to disable tty
intr. during set_keyboard(), used for changing LED and setting
typematic.

The patch also changes the function name:
    set_keyboard() -> set_keyboard_param()
Although it is a static function, the name corrides with a routine in
`syscons' and is confusing when debugging the kernel which has both
`syscons' and `pcvt' with DDB. (Suggested by Bruce)

2) doreset() bug
doreset() failed to preserve some bits in the keyboard controller's
command byte during keyboard reset. This bug may put some keyboard
controllers in old motherboards (386 and 486) in a strange state,
resulting in complete keyboard lockup or random key input.

31774f6d83 Interim patch/kludge for keyboard lock-up when `kbdcontrol' tries to
change typematic rate, or the X server (XFree86 or Accelerated X)
starts up.

So far, there have been two independent reports from Dell Latitude XPi
notebook/laptop owners. The Latitude seems to be the only system which
suffers from this problem.  (I don't know the problem is with the
entire Latitude line or with only some Latitude models) No problem
report has been heard about other systems (I certainly cannot
reproduce the problem in my -current and 2.2 systems).

In 3.0-CURRENT, 2.2-RELEASE and 2.2-GAMMA-970310, when programming the
keyboard LED/repeat-rate, `set_keyboard()' in `syscons' tells the
keyboard controller not to generate keyboard interrupt (IRQ1) and then
enable tty interrupts, expecting the keyboard interrupt doesn't occur.

It appears that somehow Latitude's keyboard controller still generates
the keyboard interrupt thereafter, and `set_keyboard()' doesn't see
the return code from the keyboard because it is consumed by the
keyboard interrupt handler.

The patch entirely disables tty interrupts while setting LED and
typematic rate in `set_keyboard()', making the routine behave more
like the previous versions of `syscons' (versions in 2.1.X and
2.2-ALPHA, -BETA, and some -GAMMAs). The reporter said this patch
eliminated the problem.

(I also found another typo/bug, but the reporter and I found that it
wasn't the cause of the problem...)

This should go into RELENG_2_2.
