no-longer-needed sys/cdefs.h includes as well as now-empty
blank lines in a row.

Remove /^#if.*\n#endif.*\n#include\s+<sys/cdefs.h>.*\n/
Remove /\n+#include\s+<sys/cdefs.h>.*\n+#if.*\n#endif.*\n+/
Remove /\n+#if.*\n#endif.*\n+/
Remove /^#if.*\n#endif.*\n/
Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/types.h>/

sys: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

cd9660: Use ANSI (c89) prototypes

Sponsored by: The FreeBSD Foundation

sys: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Fix a bunch of -Wcast-qual warnings in cd9660_util.c, by using
__DECONST. No functional change.

Use __FBSDID().

Include systm.h for panic(9) so that DEBUG_ALL_VFS_LOCKS compiles.

Revert consequences of changes to mount.h, part 2.

Requested by: bde

Correct #includes to work with fixed sys/mount.h.

Add a hook for loading of a Unicode -> char conversion routine as a kld at a
run-time. This is temporary solution until proper kernel Unicode interfaces
are in place and as such was purposely designed to be as tiny as possible
(3 lines of the code not counting comments). The port with conversion routines
for the most popular single-byte languages will be added later today

Remove unneeded #include <sys/proc.h> lines.

Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The
alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
preempted (i386 only).

$Id$ -> $FreeBSD$

The lowercasing of Joliet filenames was not a feature.

Add support for Joliet extensions to the iso9660 fs. The related PR
cannot yet be closed, though.

I hope I got all credits right, and that the multiple submitted by lines
do not break anyone's scripts...

Removed unused or apparently-unused #includes, especially of the
deprecated header <sys/dir.h>.

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

Declare function args in order in recently K&Rised function headers.

This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.

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.

There is a small bug in the cd9660 code that prevents stating of
associated files.
