Decode some more "exotic" instructions including: fxsave, fxrstor, ldmxcsr,
stmxcsr, clflush, lfence, mfence, sfence, syscall, sysret, sysenter,
sysexit, pause, monitor, mwait, and swapgs (amd64 only).

MFamd64: Decode "cmov*" instructions.

Start all license/copyright notice comments with /*-, per tradition

Fix copyright comment & FBSDID style nits.

Requested by: bde

Use __FBSDID().

Fixed some style bugs in the removal of __P(()). The main ones were
not removing tabs before "__P((", and not outdenting continuation lines
to preserve non-KNF lining up of code with parentheses. Switch to KNF
formatting and/or rewrap the whole prototype in some cases.

Remove __P.

Quiet a variable format-string warning.

$Id$ -> $FreeBSD$

Fix warnings in preparation for adding -Wall -Wcast-qual to the
kernel compile

Use not-so-new printf formats %r and/or %z instead of %n and/or %+x.

Removed a wrong comment of mine.

Removed unused #includes.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Fixed botched tables:
- the operands for bt, bts, arpl and `enter' were reversed.
- btr was reported as bts (with the correct operand order).
- cmpxchg was misplaced. It was misplaced differently in the
comments. It is misplaced differently again in the i486 manual.
I put it where the i586 manual and gas say it is.
- fucompp was misplaced.
- the rr table for(s) some versions of fstp, fcom and fcomp was non-null.
This caused some invalid opcodes to be reported as "" instead of as
"<bad instruction>".
- the word and long versions of the fi* instructions were reversed.
- aaa and daa were reversed.

Fixed bugs involving unusual operand sizes:
- 32-bit registers weren't always forced for bswap or for moves to and
from special registers.
- the operand sizes weren't reported for [l]call or [l]jmp.
- displacements weren't truncated mod 2^16 when the operand size was
16-bit.
- too-large displacements and offsets were fetched, and too-large
offsets were reported, when the operand size was 16-bit.
- sign extended immediate bytes were extended too far when the operand
size was 16-bit.

Fixed bugs involving usual operand sizes:
- 8-bit source registers weren't forced for mov[sz]b[wl].
- 16-bit source registers weren't forced for mov[sz]w[wl].
- immediate bytes were sometimes reported as sign extended even for
byte operations. Same for immediate words in word operations.
- the immediate byte was not reported as sign extended for `push'.

Finished Pentium support:
- cpuid, cmpxchg8b and rsm were missing.

Finished i287 support:
- fneni, fndisi and fsetpm were missing. These are harmless nops on
later FPUs.

Improvements:
- report invalid opcodes 0xd6 and 0xf1 using .byte. They are special
in not causing invalid operand exceptions when executed.
- report the immediate byte for unusual aam and aad instuctions.
Immediate bytes other than 0x0a always worked and are documented to
work on Pentiums.

Fixed operand order for shld and shrd.

Finished the constant poisoning that was begun in rev.1.14. Consts
aren't very poisonous (or useful) unless -Wcast-qual is in CFLAGS,
and it isn't in the default CFLAGS.

Removed bogus `altfmt' code. No alternative formats are supported, but
altfmt was abused to sometimes screw up the disassembly of the bytes
following unconditional jump instructions. Gas doesn't pad to a longword
boundary like the comment said - that is the programmer's responsibility.

Teach the disassembler about the 0f,3x family of instructions
(RDMSR, RDTSC, WRMSR, and RDPMC).

Get rid of two and a half printf in the kernel.
Add more features to the one remaining to handle the job:
+ signed quantity.
# alternate format
- left padding
* read width as next arg.
n numeric in (argument specified) default radix.

Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.

The warnings from gcc may become more wrong and intolerable because
of this.

Warning: I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

Suggested by: bde

Untangled the vm.h include file spaghetti.

Removed bogus statics in declarations that don't allocate storage.

Added prototypes.

Second batch of cleanup changes.
This time mostly making a lot of things static and some unused
variables here and there.

Remove trailing whitespace.

Fix disassembly of `bt[crs] $Ib,E'.

db_disasm.c: Unused var zapped.
pmap.c: tons of unused vars zapped, various other warnings silenced.
trap.c: unused vars zapped.
vm_machdep.c: A wrong argument, which by chance did the right thing, was
corrected.

Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles. This is not
quite complete yet, as `config' doesn't yet do the right thing. You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make

Make everything compile with -Wtraditional. Make it easier to distribute
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.

Make the LINT kernel compile with -W -Wreturn-type -Wcomment -Werror, and
add same (sans -Werror) to Makefile for future compilations.

Removed all patch kit headers, sccsid and rcsid strings, put $Id$ in, some
minor cleanup. Added $Id$ to files that did not have any version info, etc

Fixed two occarances of ldos which should have been lods.
