81f7ff2872 Delay mp_start() till after the msgbuf is mapped. We really want to delay
it till even later but tss setup prevents that right now...

5a1c8ae0ba Convert all:
panic( "xxxxx\n" );

to:
 printf( "xxxxx\n" );
 panic( "\n" );

For some as yet undetermined reason the argument to panic() is often NOT
printed, and the system sometimes hangs before reaching the panic printout.
So we hopefully at least print some useful info before the hang, as oppossed to
leaving the user clueless as to what has happened.

9d49e3ca10 This commit affects ELF kernels only.
Remove "setdefs.h" and arrange to generate it automatically at
ELF kernel build time.

"gensetdefs.c" is a utility which scans a set of ELF object files
and outputs a line ``DEFINE_SET(name, length);'' for each linker
set that it finds.  When generating an ELF kernel, this is run just
before the final link to generate "setdefs.h".

Remove the init_sets() function from "setdef0.c", and its call from
"machdep.c".  Since "gensetdefs.c" calculates the length of each
set, it is no longer necessary in an ELF kernel to count the set
elements at kernel initialization time.  Also remove "set_of_sets"
which was used for this purpose.

Link "setdef0" and "setdef1" into the kernel only if building for
ELF.  Since init_sets() is no longer used, there is no need to link
them into an a.out kernel.

0d42d75ea0 Make setbits() SMP-safe. Eliminate the SETBITS() macro, and replace
all uses of it with the equivalent calls to setbits().

This change incidentally eliminates a problem building ELF kernels
that was caused by SETBITS.

6ea632b44d Bring in some kernel bootp support. This removes the need for netboot
to fill in the nfs_diskless structure, at the cost of some kernel
bloat. The advantage is that this code works on a wider range of
network adapters than netboot. Several new kernel options are
documented in LINT.
Obtained from: parts of the code comes from NetBSD.

7ed868f1de Fixed initialization of ldt[]. Unused entries were garbage. A comment
was stale.

Fixed initialization of gdt[] for the BDE_DEBUGGER case.  APM entries
clobbered debugger entries if the debugger was loaded (APM is incompatible
with BDE_DEBUGGER) and unused entries were garbage if the debugger wasn't
loaded.

1f075493b1 Don't allow access to illegal addresses in /dev/kmem to panic kernel
(eg: above 0xffc00000).  Programs using /dev/kmem are implicitly racing
the kernel, and can get right up high in memory.  I've been running
these for some time now, but with printfs.  It's saved two panics at
least that I can remember.

27b2936ad3 clean up forked child creation. This is simplified also by having
md_regs being struct trapframe *.  Do a npxsave() if needed and copy the
pcb rather than use the increasingly defunct savectx().  Copy %edi and
%ebp explicitly.

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
simplifies some assumptions and stops some code compile problems.

This should fix the compile hiccup in PR#3491, but smp kernel profiling
isn't likely to be fixed by this.
