IMO the issue is that your patch makes the code (including the XTS code)
inconsistent because it makes it use a mix of both approaches: it aligns each
field individually, *and* it aligns the ctx up-front.

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,
