Kompilace linux kernel modulu

Zdravim, chtel bych se naucit programova linux kernel moduly.Nasel jsem spoustu tutorialu jak na to, napr:

http://www.freesoftwaremagazine.com/articles/drivers_linux?page=0%2C2

Ten uvodni hello world priklad je skoro vsude stejny, ale problem je, ze mi nejde zkompilovat. Tusim, ze to bude tim, ze vsechny tyto clanky jsou uz starsiho data a priklady jsou tedy urceny pro starsi kernely. Rad bych modul zkomplioval u sebe na 2.6.39.4, ale nikde jsem nenasel tutorial urceny pro novejsi jadra, muzete mi prosim poradit?

Dekuji bylo to tedy tim makefilem, ktery jsem mel spatne. Jednoduchy hello world modul funguje, ja bych rad ale zkompiloval napriklad toto:

Jde mi o to, zachytit nejakou systemovou funkci. Vyse uvedeny priklad (adresu sys_call_table jsem upravil dle sveho systemu) mi pri kompilaci hlasi:
