Including linux kernel headers into userspace apps is always a bad idea 
because when a problem happens kernel hackers will tell you "Do not ever 
include kernel headers in userspace". But if you have to do this ( and you 
have to because you need to access video device apparently ) never include 
asm/foo.h but include linux/foo.h equivalent.
