compile error in 2.4.0

[Alan Chandler]

I'm probably doing something silly, but I have just tried to rebuild
the 2.4.0 kernel.  I changed a few config things and did

make dep clean bzlilo modules modules_install

and the following appeared.  I did a brief look around for the
declaration of skb_datarefp but couldn't find it.
