d021fc112b 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.

1f8745a9c3 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.

Submitted by: bde

XXX npxproc could be declared in npx.h so the externs with smp fruit
are not needed.

914970e6e9 md_regs is struct trapframe * now, rather than int []
Remove TF_REGP() macro and use.  The original reason (address space
problems due to having UPAGES in mapped into user space) is gone.  It
looks cleaner without it.

cea6c86c11 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.

5adee135aa Duplicate the TOC handling ioctls from the cd(4) driver. Duplicating
the work is silly, and all this will be a moot point with Justin's CAM
driver, and there are still many ioctls missing -- but i need these
right now.  It's silly to need to move the CD-R back to the other
drive in order to determine the session start info when burning multi-
session CD-Rs.

62102247f6 Oops. The function cd9660_mountroot() is gone, but i've committed an

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.

Peter Wemm
26e5316524 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.
