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. Reviewed by: Bruce Evans

extern const struct execsw coff_execsw;
`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.

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.

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.
