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.
