Hi all ,
I have  a driver and when i am doing insmod the driver its giving 
unresolved symbol.

insmod: unresolved symbol copy_to_user
insmod: unresolved symbol down
insmod: unresolved symbol up
insmod: unresolved symbol copy_from_user

Can anyone suggest me where i am doing wrong.
I am using linux-2.4.25 kernel from denx and my board is a 
customboard(mpc8260 processor).
This is a upm driver and built as a loadable module.

Please help me in this regard
Thanks in advance.
