7485dac765 Make MOD_* macros almost consistent:
Use the name argument almost the same in all LKM types.  Maintain
the current behavior for the external (e.g., modstat) name for DEV,
EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only
#name.  This is a candidate for change and I vote just the name without
the "_mod".

Change the DISPATCH macro to MOD_DISPATCH for consistency with the
other macros.

Add an LKM_ANON #define to eliminate the magic -1 and associated
signed/unsigned warnings.

Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure.

Change source in tree to use the new interface.

808a36ef65 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.

325338fe3d `struct linker_set execsw_set' was declared as const and pointers in it
were declared as non-const.  This is backwards (_lkm_exec() changes the
pointers but all the target `struct execsw's are const).  Fixed this
and poisoned related declarations to match and removed the bogus casts
that hid the bug.

ad719447f5 Fixed the `machine' link. It pointed to the wrong place, and was created
too late to be used in all cases.  It should probably be created (early)
in bsd.kmod.mk for all LKMs.

Use cc instead of cpp | as for the same reasons as in the kernel makefile.
CFLAGS isn't split up as well as in the kernel makefile, but cc doesn't
pass compiler warning flags to cpp, so there is no need to split it.

35ed39b537 linux_interp now moved into sys/i386/linux/linux_sysvec.c, but still
connected at load and unload time from here.

7d151a09c3 First attempt at FreeBSD & Linux ELF support.
Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.

To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.

The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.
(No it won't run quake yet :)

744710a9af Update the linux lkm to use the new file list and build routine.
This is a bit of a kludge and needs more work.

7d1993a61c No longer generate empty opt_sysvipc.h, and no longer issue -DSYSVSHM etc
for the CFLAGS.  Now, it tracks whatever the booted kernel has rather than
being specifying what features your kernel has at lkm build time.

b9f0e11d4a Changed the first (name) arg of MOD_DEV(), MOD_EXEC() and MOD_MISC()
from a string to an identifier so that it can be used to generate
declarations and strings.  It's much easier to stringize an identifier
than to identifize a string.  A uniform naming scheme must be used
for the automatically generated things to apply.  This is a feature.

Used the module identifer to generate prototypes for the module load,
unload and stat functions.  Removed the few prototypes for these that
already existed.

Used the module identifier to generate a unique struct tag in MOD_DEV().
This should probably be done for all the MOD_*() macros.

Moved the trailing semicolon from the MOD_*() macro definitions to the
macro invocations that didn't already (bogusly) have it.

Staticized the module load and unload functions.

Added function return types for the module load, unload and stat functions.

lkm/ibcs2/ibcs2.c:
Included <sys/sysproto.h> to get everything prototyped.
Cleaned up #includes.

lkm/ibcs2/ipfw.c:
Cleaned up #includes.

lkm/linux/linux.c:
The module name had to change from "linux_emulator" to "linux_mod" to
be automatically generated.
Cleaned up #includes.

lkm/syscons/*/*_saver.c:
Completed delcarations of function pointers.

sys/i386/isa/atapi.c:
The module name had to change from "atapi" to "atapi_mod" to be
automatically generated.

sys/i386/isa/wcd.c:
Used the fixed MOD_DEV().  This module has two devices and expanded the
macro in the source instead of fixing it.
The module names had to change from "wcd" and "rwcd" to "wcd_mod" and
"rwcd_mod" to be automatically generated.

sys/pccard/pcic.c:
The module name had to change from "pcic" to "pcic_mod" to be
automatically generated.

4d0291b75b Replaced nosys() by lkm_nullcmd(). Always call lkm load/unload/stat
functions instead of skipping the call if the function is nosys().
nosys() returned the wrong value as well as having the wrong type.

cb39a8365e Do a pass over the broken LKM's and update them to use the "new"
convention of having their entry point named "<modname>_mod"".
Symorder is enforcing this when the current bsd.kmod.mk is installed.

I've not tested all these, but at least they all compile now.

Reattach them to the makefile.

Note that the change that I made to symorder needs to be compiled and
installed before any LKM's will work - the last version was corrupting
the relocation tables.  A "make world" will to this, but if you
manually run a make on the lkm's you'll need to take care of it by
hand.

f14ea10694 First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).

Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.

Kernel must be compiled with "options COMPAT_LINUX" for this to work.
