02b199f158 Link ALTQ to the build and break with ABI for struct ifnet. Please recompile
your (network) modules as well as any userland that might make sense of
sizeof(struct ifnet).
This does not change the queueing yet. These changes will follow in a
seperate commit. Same with the driver changes, which need case by case
evaluation.

__FreeBSD_version bump will follow.

a55624165f Remove "-frename-registers" option for sparc64 kernel builds. That
was not present in what I originally tested when checking to see if
the kernel built/ran with the -O2 change.  Recent instability in
sparc64 kernel was tracked to this.  A reproducible kernel stack
traceback followed by hard hang during the call to msleep() at the
point the kernel waits 15 seconds for the SCSI bus to settle crept in
to recent kernel builds and it seems to go away with this patch.

8bbf57a9c8 For AMD64, lets officially support a -O2 kernel build!
I've added -fno-strict-aliasing for now so we can ease into this.
I wanted to shoot for -O3, but the inlining caused problems due to GCC's
size heuristics; so also add -frename-registers, which is one of the things
-O3 would have given us.

06d6e4fcfe This are the build infrastructure changes to allow to use the
Intel C/C++ compiler (lang/icc) to build the kernel.

The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but
doesn't abort. They also produce CPU specific code (new instructions
of the CPU, not only CPU specific scheduling), so if you get coredumps
with signal 4 (SIGILL, illegal instruction) you've used the wrong
CPUTYPE.

Incarnations of this patch survive gcc compiles and my make universe.
I use it on my desktop.

To use it update share/mk, add
	/usr/local/intel/compiler70/ia32/bin	(icc v7, works)
or
	/usr/local/intel_cc_80/bin		(icc v8, doesn't work)
to your PATH, make sure you have a new kernel compile directory
(e.g. MYKERNEL_icc) and run
	CFLAGS="-O2 -ip" CC=icc make depend
	CFLAGS="-O2 -ip" CC=icc make
in it.

Don't compile with -ipo, the build infrastructure uses ld directly to
link the kernel and the modules, but -ipo needs the link step to be
performed with Intel's linker.

Problems with icc v8:
 - panic: npx0 cannot be emulated on an SMP system
 - UP: first start of /bin/sh results in a FP exception

817b59bff6 Reduce the number of knobs controlling the build of debug modules
to one, DEBUG_FLAGS, which is also compatible with <bsd.prog.mk>.
Previously one had to set both DEBUG and DEBUG_FLAGS to build the

2c737393a1 Backed out a small part of rev.1.15. -Winline now works better, so
there is no need turn it off when compiling with -finstrument-functions.

Having -Winline turned off mainly broke checking for bogus inlines in
kernels configured with high resolution profiling, e.g., LINT.  Not
turning it off unbreaks the warnings for bogus inlines in istallion.c,
but at least the i386 LINT still builds because istallion.c is compiled
without -Werror due to other bugs in it.

d00ce91973 Moved $FreeBSD$ to the beginning of the file.
Don't put the name of the file in a comment.  $FreeBSD$ gives more than

Fixed misdescription of the file.  It isn't the whole unified Makefile...

5064105e52 Move the inline limit default variable to a per-arch place. For example,
the amd64 implementation of the pcpu macros is even more verbose than on
i386 and that causes gcc to way overestimate the complexity of this
2-instruction macro.  The other platforms can probably lower their
default values.

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

3c9d896571 Quick fix for high resolution kernel profiling on i386's. Use
-finstrument-functions instead of -mprofiler-epilogue.  The former
works essentially the same as the latter but has a higher overhead
(about 22 more bytes per function for passing unused args to the
profiling functions).

Removed all traces of the IDENT Makefile variable, which had been
reduced to just a place for holding profiling's contribution to CFLAGS
(the IDENT that gives the kernel identity was renamed to KERN_IDENT).

2faccca61a Turn on -Werror by default. This is is easily turned off, by either:
- fix the warnings, they are there for a reason!
- add -DNO_ERROR to your make(1) command.
- add 'makeoptions NO_WERROR=true' to your kernel config.
- add 'nowerror' to conf/files* that have warnings that should be fixed
  due to tracking 3rd party vendor code.
- add 'nowerror' to conf/files* where the warning is false due to a
  compiler bug and fixing it with brute force would be too expensive.

There are some very sloppy warnings in our kernel build, come on folks!

'make release' uses -DNO_WERROR intentionally.

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.

Mike Smith
0b3178a45c Eliminate the use of commons in the kernel and modules,
simplifying the module linking process and eliminating the risks
associated with doubly-defined variables.

Cases where commons were legitimately used (detection of
compiled-in subsystems) have been converted to use sysinits, and
any new code should use this or an equivalent practice as a
matter of course.

Modules can override this behaviour by substituting -fno-common
out of ${CFLAGS} in cases where commons are necessary
(eg. third-party object modules).  Commons will be resolved and
allocated space when the kld is linked as part of the module
build process, so they will not pose a risk to the kernel or
other modules.

Provide a mechanism for controlling the export of symbols from
the module namespace.  The EXPORT_SYMS variable may be set in the
Makefile to NO (export no symbols), a list of symbols to export,
or the name of a file containing a newline-seperated list of
symbols to be exported.  Non-exported symbols are converted to
local symbols.  If EXPORT_SYMS is not set, all global symbols are
currently exported.  This behaviour is expected to change (to
exporting no symbols) once modules have been converted.
