 *
 *	For functions which are either STUBs or WSTUBs the actual function
 *	need to be called using 'call' instruction because of preamble and
 *	postamble (i.e mod_hold_stub and mod_release_stub) around the
 *	function call. Due to this we need to copy arguments for the
 *	real function. On Intel we can't tell how many arguments are there
 *	on the stack so we have to either copy everything between esp and
 *	ebp or copy only a fixed number (MAXNARG - defined here) for
 *	all the stub functions. Currently we are using MAXNARG (it is a kludge
 *	but worth it?!).
 *
 *	NOTE: Use NO_UNLOAD_STUBs if the module is NOT unloadable once it is
 *	      loaded.

 * WARNING: there is no check for forgetting to write END_MODULE,
 * and if you do, the kernel will most likely crash.  Be careful
 *
 * This file assumes that all of the contributions to the data segment
 * will be contiguous in the output file, even though they are separated
 * by pieces of text.  This is safe for all assemblers I know of now...
 */

/*
 * This file uses ansi preprocessor features:
 *
 * 1.   #define mac(a) extra_ ## a     -->   mac(x) expands to extra_a
 * The old version of this is
 *      #define mac(a) extra_/.*.*./a
 * but this fails if the argument has spaces "mac ( x )"
 * (Ignore the dots above, I had to put them in to keep this a comment.)
 *
 * 2.   #define mac(a) #a             -->    mac(x) expands to "x"
 * The old version is
 *      #define mac(a) "a"
 *
 * For some reason, the 5.0 preprocessor isn't happy with the above usage.
 * For now, we're not using these ansi features.
 *
 * The reason is that "the 5.0 ANSI preprocessor" is built into the compiler
 * and is a tokenizing preprocessor. This means, when confronted by something
 * other than C token generation rules, strange things occur. In this case,
 * when confronted by an assembly file, it would turn the token ".globl" into
 * two tokens "." and "globl". For this reason, the traditional, non-ANSI
 * preprocessor is used on assembly files.
 *
 * It would be desirable to have a non-tokenizing cpp (accp?) to use for this.
