Submitted by: Jason Bacon <bacon at smithers dot neuro dot mcw dot edu>

Assorted markup, spelling, and grammar fixes.

- Update for the new interrupt code on i386 meaning that SMP kernels can
now run on UP machines, options APIC_IO is now spelled device apic, and
HT CPUs are now enabled by default.
- Add a 'I386 NOTES' section header to the i386-specific paragraphs.
Someone with more mdoc fu can suggest a better name if needed.

Hiten's patchset for section four manpages, slightly edited by me.

- Don't highlight options APIC_IO at the top since it only applies to i386
and this manpage is somewhat machine independent.
- Don't redundantly say that SMP support is present for all supported
architectures. Instead, say that it is present for all Tier-1
architectures.
- Note that an SMP kernel not booting on a UP machine is an i386-only
exception.
- Add a paragraph about hyperthreading support including some docco on the
machdep.hlt_logical_cpus sysctl ps@ recently added.
- Note that SMP support for alpha, ia64, and sparc64 debuted in 5.0.

mdoc(7) police: markup nits.

Provide enhanced information on configuring SMP support in a kernel.

Approved by: re

Take a pass at updating this man page a bit to at least mention SMPng,
that we do MP on more than just i386, and add some cross-references.
This is far from a perfect update, but at least it's a start. More
will no doubt follow.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

$FreeBSD$ tags moved to bottom of license aggmt.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
