Module source should look like this:

  single .c -> single .o

    #include <linux/kernel.h>
    #include <linux/module.h>

  multiple .c -> single .o, main .c file (contains init_module(), etc.)

    #include <linux/kernel.h>
    #include <linux/module.h>

  multiple .c -> single .o, secondary .c file

    #include <linux/kernel.h>

  multiple .c -> single .o, secondary .c file that requires module.h
  for a particular purpose, such as EXPORT_SYMBOL()

    #define __NO_VERSION__
    #include <linux/kernel.h>
    #include <linux/module.h>

Note that in most cases, you _don't_ need to include module.h.

Your Makefile should call gcc with '-D__KERNEL__ -DMODULE', as well
as other approprate flags.
