Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 

Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

  API:
   - A large number of bug fixes for the af_alg interface, credit goes
     to Dmitry Vyukov for discovering and reporting these issues.

  Algorithms:
   - sw842 needs to select crc32.
   - The soft dependency on crc32c is now in the correct spot.

  Drivers:
   - The atmel AES driver needs HAS_DMA.
   - The atmel AES driver was a missing break statement, fortunately
     it's only a debug function.
   - A number of bug fixes for the Intel qat driver"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (24 commits)
  crypto: algif_skcipher - sendmsg SG marking is off by one
  crypto: crc32c - Fix crc32c soft dependency
  crypto: algif_skcipher - Load TX SG list after waiting
  crypto: atmel-aes - Add missing break to atmel_aes_reg_name
  crypto: algif_skcipher - Fix race condition in skcipher_check_key
  crypto: algif_hash - Fix race condition in hash_check_key
  crypto: CRYPTO_DEV_ATMEL_AES should depend on HAS_DMA
  lib: sw842: select crc32
  crypto: af_alg - Forbid bind(2) when nokey child sockets are present
  crypto: algif_skcipher - Remove custom release parent function
  crypto: algif_hash - Remove custom release parent function
  crypto: af_alg - Allow af_af_alg_release_parent to be called on nokey path
  crypto: qat - update init_esram for C3xxx dev type
  crypto: qat - fix timeout issues
  crypto: qat - remove to call get_sram_bar_id for qat_c3xxx
  crypto: algif_skcipher - Add key check exception for cipher_null
  crypto: skcipher - Add crypto_skcipher_has_setkey
  crypto: algif_hash - Require setkey before accept(2)
  crypto: hash - Add crypto_ahash_has_setkey
  crypto: algif_skcipher - Add nokey compatibility path
