            gcc-3.4.3 and gcc-3.4.1 do not currently support forward
    declaration of inline functions, as is used in
    linux-2.6.10-rc2/drivers/crypto/padlock-aes.c.

            The function is trivial, so it is better to inline it
    by defining it earlier than it would be to un-inline it.
    Here is a proposed patch. If it looks okay, I would appreciate
    it if someone would bless it and forward it downstream.
