| |
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.
