a problem of kernel-module version mismatch.

Thanks for your telling first.

Sorry that I am a novice in Linux. I don't know how can I put the driver in 
my source tree and compile everything together. It looks like that there is 
no option in the menuconfig to choose a specially customed peripheral. So I 
think I only can include the customed peripheral as a module. Could you 
please say in a detail on how to do that?

It's very strange because I have checked the source. In the header file of 
xio.h, there are the following sentences,

/************************** Function Prototypes 
******************************/

/* The following functions allow the software to be transportable across
 * processors which may use memory mapped I/O or I/O which is mapped into a
 * seperate address space such as X86.  The functions are better suited for
 * debugging and are therefore the default implementation. Macros can 
instead
 * be used if USE_IO_MACROS is defined.
 */
#ifndef USE_IO_MACROS

/* Functions */
Xuint8 XIo_In8(XIo_Address InAddress);
Xuint16 XIo_In16(XIo_Address InAddress);
Xuint32 XIo_In32(XIo_Address InAddress);

void XIo_Out8(XIo_Address OutAddress, Xuint8 Value);
void XIo_Out16(XIo_Address OutAddress, Xuint16 Value);
void XIo_Out32(XIo_Address OutAddress, Xuint32 Value);

#else

/* The following macros allow optimized I/O operations for memory mapped 
I/O
 * Note that the SYNCHRONIZE_IO may be moved by the compiler during
 * optimization.
 */

#define XIo_In8(InputPtr)  (*(volatile Xuint8  *)(InputPtr)); 
SYNCHRONIZE_IO;
#define XIo_In16(InputPtr) (*(volatile Xuint16 *)(InputPtr)); 
SYNCHRONIZE_IO;
#define XIo_In32(InputPtr) (*(volatile Xuint32 *)(InputPtr)); 
SYNCHRONIZE_IO;

#define XIo_Out8(OutputPtr, Value)  \
    { (*(volatile Xuint8  *)(OutputPtr) = Value); SYNCHRONIZE_IO; }
#define XIo_Out16(OutputPtr, Value) \
    { (*(volatile Xuint16 *)(OutputPtr) = Value); SYNCHRONIZE_IO; }
#define XIo_Out32(OutputPtr, Value) \
    { (*(volatile Xuint32 *)(OutputPtr) = Value); SYNCHRONIZE_IO; }

#endif

I think these are the defination of XIo_In32 and XIo_Out32. Also, during 
the compilation, there is no error to complain that "XIo_In32 or XIo_Out32 
undeclared". 

More suggestions are appreciated. Thanks.
