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
