Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu: "This push fixes a number of crashes triggered by a previous crypto self-test update. It also fixes a build problem in the caam driver, as well as a concurrency issue in s390. Finally there is a pair of fixes to bugs in the crypto scatterwalk code and authenc that may lead to crashes" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: testmgr - fix sglen in test_aead for case 'dst != src' crypto: talitos - fix aead sglen for case 'dst != src' crypto: caam - fix aead sglen for case 'dst != src' crypto: ccm - Fix handling of zero plaintext when computing mac crypto: s390 - Fix aes-xts parameter corruption crypto: talitos - corrrectly handle zero-length assoc data crypto: scatterwalk - Set the chain pointer indication bit crypto: authenc - Find proper IV address in ablkcipher callback crypto: caam - Add missing Job Ring include
