a5c67c037d This is the kernel linker. To use it, you will first need to apply
the patches in freefall:/home/dfr/ld.diffs to your ld sources and set
BINFORMAT to aoutkld when linking the kernel.

Library changes and userland utilities will appear in a later commit.

97abe7f4c6 Now that we have replaced video-related block copy calls with
sc_bcopy(), which is generic_bcopy() in reality, there is no point in
retaining bcopyw() calls in the source code.

8cea5b917d 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.

359b54a79a Don't remove i586_ctr_freq from scope, leave it defined as zero. This

a04669c796 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

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

6323aa10bf 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!
