But, the code did this already:

common_rfc4106_set_key()
-> aesni_rfc4106_gcm_ctx_get(aead) 	// align ->ctx
-> aes_set_key_common()
    -> aes_ctx()				// here, this aligns again

And generic_gcmaes_set_key() as well.

Hmm, maybe a separate patch can spell out this issue more clearly for 
the record, no?

Thanks,
Chang
