Revert config(8) version bump. It brings major pain for people working on
different versions of FreeBSD source tree.

Old config(8) can now be used unless you want to use INCLUDE_CONFIG_FILE
option.

Bump config(8) version and build requirement for config(8) to 600006. This
is caused by my latest changes to config(8). You're supposed to install new
config(8) in order to prevent yourself from seeing a warning about old
version of that tool.

You should configure the kernel with a new config(8) then.

Version 600004 is better than 700000 given other changes that are in
the pipeline. We had to bump the version for 600004 because the old
parser got confused and generated bogus output.

Make config(8) understand ORed dependecies in "files*" and
improve tracking of known devices. Bump config(8) version.

We don't bump the config version for additions to config that aren't
used in the base system. This has been much discussed in the past
(typically people giving me a hard time for it). Since all that was
added to config was nocpu, and since we don't use it, we don't need to
bump the version.

Implement the "nocpu" directive.

Bump config(8) version for the DEFAULTS change.

Never hardcode /sys into these Makefiles. The proper way to spell it is $S.

Also, move the -I stuff to the centralized kern.pre.mk. However, it
might be better to add these flags to files.conf. This is a short
term fix to fix the broken builds on my machine (I don't have a valid
/sys link).

The latest release of the FreeBSD driver (twa) for
3ware's 9xxx series controllers. This corresponds to
the 9.2 release (for FreeBSD 5.2.1) on the 3ware website.

Highlights of this release are:

1. The driver has been re-architected to use a "Common Layer"
(all tw_cl* files), which is a consolidation of all OS-independent
parts of the driver. The FreeBSD OS specific portions of the
driver go into an "OS Layer" (all tw_osl* files).
This re-architecture is to achieve better maintainability, consistency
of behavior across OS's, and better portability to new OS's (drivers
for new OS's can be written by just adding an OS Layer that's specific
to the OS, by complying to a "Common Layer Programming Interface" API.

2. The driver takes advantage of multiple processors.

3. The driver has a new firmware image bundled, the new features of which
include Online Capacity Expansion and multi-lun support, among others.
More details about 3ware's 9.2 release can be found here:
http://www.3ware.com/download/Escalade9000Series/9.2/9.2_Release_Notes_Web.pdf

Since the Common Layer is used across OS's, the FreeBSD specific include
path for header files (/sys/dev/twa) is not part of the #include pre-processor
directive in any of the source files. For being able to integrate twa into
the kernel despite this, Makefile.<arch> has been changed to add the include
path to CFLAGS.

Update version number for latest config version bump

bump the Makefile config versions now that config is 600001...

Forgotten by: des

Kill count device support from config. I've changed the last few
remaining consumers to have the count passed as an option. This is
i4b, pc98/wdc, and coda.

Bump configvers.h from 500013 to 600000.

Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device. This broke things like the snd_emu10k1 device, which required
quotes to make it parse right. The no-longer-needed quotes have been
removed from NOTES, GENERIC etc. eg, I've removed the quotes from:
device snd_maestro
device "snd_maestro3"
device snd_mss

I believe everything will still compile and work after this.

Change required config(8) version.

Bump the config version to force people to upgrade their config(8)
so the fix for emitting multiple instances of .o files will prevent
link errors on LINT.

Standardize handling of locore.[sS] etc. files.

- Removed various cruft from before we had a hosted toolchain (!).
- Moved special compiler flags to bsd.kern.mk so they get used for modules
too.

Include majors.o in SYSTEM_OBJS to make sparc64 kernels link. This is a
quick fix while I work on a better solution.

Moved most interrupt related code to a new file, interrupt.S.

*.s -> *.S.

Moved the rule for locore.o from kern.post.mk to Makefile.$ARCH.

Moved the setting of all profiling-related variables except the key one
(PROFLEVEL) to kern.pre.mk so that it is easier to manage. Bumped config
version to match.

Moved the check for cputype being configured to a less bogus place in
mkmakefile.c.

Remove a hack for using an external compiler if cross compiling.

MFP4. This slipped into a IFC(MFC) by PHK, but it could still be useful
To commit it for real.

Remove all the custom toolchain knob tweaking.
We are now using a native binutils, and you have to have CC=gcc in your
/etc/make.conf to compile userland anyway.

Use the deo hosted toolchain by default.

Commit some infrastructure for turning on -Werror for kernel compiles.
It doesn't actually do it yet though. This adds a flag to config so
that we can exclude certain vendor files from this even when the rest
of the kernel has it on. make -DNO_WERROR would also bypass all of it.

Add -mcmodel=medlow to COPTS. This is needed to build working kernels.

Proper fix for old config setting maxusers to 8.

Change to using my custom sparc64 binutils.

Move kern.post.mk to last line, now that it appears safe

Factor the common parts of the Makefile.foo files. This introduces two
new files: kern.pre.mk, which contains most of the definitions, and
kern.post.mk, which contains most of the rules.

I've tested this on i386 and pc98. I have had feedback on the sparc64
port, but no reports from anybody on alpha, ia64 or powerpc. I
appologize in advance if I've broken you.

Only overwrite ${DESTDIR}${KODIR}.old/${KERNEL_KO} if we haven't
booted from it when doing an installkernel.

Only change kern.bootfile from ${DESTDIR}${KODIR}/${KERNEL_KO}
to ${DESTDIR}${KODIR}.old/${KERNEL_KO}, and only when we're renaming
a booted ${DESTDIR}${KODIR}/${KERNEL_KO} kernel.

Support the "install.debug" and "reinstall.debug" targets for kernel modules.
Small tweaks to kldxref may be necessary to avoid the surprising (but harm-
less) behaviour of 'kldload foo' loading foo.ko.debug instead of foo.ko if
it is present in the kernel directory.

Enable hardwiring of things like tunables from embedded enironments

In order to bring about the end of the universe, delete the lines:
# DO NOT DELETE THIS LINE -- make depend uses it

Add code model medlow to cflags and move the kernel load address from
just before the memory hole to 4 megs. Special case building exception.s
like locore.s, it needs to at the beginning so the branches out from the
trap table don't overflow.

Add a Makefile, ldscript, and config magic for sparc64. This is tailored
to build with a cross compiler alongside the standard compiler; it would be
more desirable to build in a chroot.
