Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Add section .note.GNU-stack for assembly files used by 386 and amd64.

Remove unneeded stores back into the function arguments.

Submitted by: Christoph Mallon

Add missing END() macros, as per rev 184547 for amd64. The lack of these
is mostly harmless, but it does upset some of valgrind's functionality.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Back out the -fpcc-struct-return fixes.

Approved by: re (rwatson)

Import newer versions of div() and ldiv() from NetBSD which handle
the -fpcc-struct-return calling convention properly instead of
returning garbage. This may break backwards compatibility with some old
binaries that were compiled when -fno-pcc-struct-return was the default.

Standardize on our SCM ID style.

De-orbit DEFS.h - the other arches do not use it, and it got replaced
with <machine/asm.h>.

Removed duplicate VCS ID tags, as per style(9).

$Id$ -> $FreeBSD$

Revert $FreeBSD$ to $Id$

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.

First crack at making libc work with the new make macros. It compiles on
my machine, and a simple static (genassym) and shared (sysctl) executable
both work. Still to be done: RPCand YP merge.
