[CRYPTO] Ensure cit_iv is aligned correctly
This patch ensures that cit_iv is aligned according to cra_alignmask by allocating it as part of the tfm structure. As a side effect the crypto layer will also guarantee that the tfm ctx area has enough space to be aligned by cra_alignmask. This allows us to remove the extra space reservation from the Padlock driver. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
