From fbdae9f3e7fb57c07cb0d973f113eb25da2e8ff2 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 6 Jul 2005 13:53:29 -0700 Subject: [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 Signed-off-by: David S.
