664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

f3086365a3 Put I*86_CPU options in opt_global.h and don't #include "opt_cpu.h"
centrally.

8bd28861d8 Fixed linting of and compilation of the gcc byte-swapping macros
properly.  Simply don't use the gcc macros if we're not gcc, and
declare prototypes for the byte-swapping functions in case the
macro versions are not used.  The previous fix was wrong and broke
libpcap, which abuses -Dlint.

Don't pollute the namespace if _POSIX_SOURCE is defined.  This is
broken - it makes almost everything in <machine/endian.h> inaccessible
if _POSIX_SOURCE is defined, yet <machine/endian.h> is not a POSIX
header.  Other systems don't do it any better.

Removed always-false `BYTE_ORDER == BIG_ENDIAN' ifdef.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

1130b656e5 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.

807cf4006d Make LKM's build again. I have added the allegedly broken
ACTUALLY_LKM_NOT_KERNEL until the real fix comes through.  Whatever
flag that is used to indicate building LKMs will have be be substituted
in the future.  This allows proper selection of the usage of the
efficient, single instruction in the kernel, but alas, doesn't allow
for use in userland or LKMs :-(.  Them's the breaks!!!

66f61b8256 Change endian.h so that when a kernel is compiled without I386_CPU, and
with one of the following (I486_CPU,I586_CPU,I686_CPU) so it can take
advantage of the very quick bswap insn.  This keeps LKMs from being
built to take advantage of the insn, but also makes sure that the LKMs
can be run on all CPUs.  (The LKMs don't pick up the CPU options :-( ).

6f235fb2f9 Relax the constraints on the bswap opcode (it works on non-byte
registers.)  Also clean up some namespace pollution, and remove
gcc-1 support (nothing really works with it anymore anyway.)

f8b4081443 Support the appropriate use of bswap instruction on non-I386 builds.
Per Wayne Scott of Intel, the old sequence took 20cycles!!! on a P6.
Another nice side-benefit is that the kernel is about 3K smaller!!!

bbabe47be8 When compiling with '-Wall -pedantic', the byte swapping macros gave the
following warning:
  warning: ANSI C forbids braced-groups within expressions

Adding __extension__ before the statement-expression seems to work right.

6e393973f5 Made all header files idempotent and moved incorrect common data from
headers into a related source file.  Added cons.h as first step towards
moving i386/i386/cons.h to machine/cons.h where it belongs.

34a8ed1be1 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
