Description of problem:
Using the kernel source shipped with RH 7.1, I had to add a #include to
include/linux/module.h in order to compile drivers/sound/soundcore.c. 
Dunno if this is the optimal solution.

I'm surprised a file called "rhconfig.h" has to exist -- I would hope that
all distributions would share identical kernel source.

Below are the first few lines of module.h, showing the #include added:

/*
 * Dynamic loading of modules into the kernel.
 *
 * Rewritten by Richard Henderson <rth@tamu.edu> Dec 1996
 */

#ifndef _LINUX_MODULE_H
#define _LINUX_MODULE_H

/* new addition */
#include <linux/rhconfig.h>
/* end new addition */
#include <linux/config.h>
#include <linux/spinlock.h>
#include <linux/list.h>

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. in /usr/src/linux, choose sound support as a module
2. run "make clean; make dep; make; make modules"
3. notice that soundcore.c failed to compile

Expected Results:  no error messages

Additional info:

Here's the cpp output showing why rhconfig.h has to be included before line
173 of module.h.  (rhconfig.h does get included on line 256 of module.h, by
way of version.h.)

# 173 "/usr/src/linux/include/linux/module.h"
extern void inter_module_register_R_ver_str(62dada05)(const char *, struct
module *, const void *);
