  Initialization of cra_list is currently mixed, most ciphers initialize this
  field and most shashes do not. Initialization however is not needed at all
  since cra_list is initialized/overwritten in __crypto_register_alg() with
  list_add(). Therefore perform cleanup to remove all unneeded initializations
  of this field in 'arch/x86/crypto/'.

  x86 has fast unaligned accesses, so blowfish-x86_64 does not need to enforce
  alignment.

  Combine all crypto_alg to be registered and use new crypto_[un]register_algs
  functions. Simplifies init/exit code and reduce object size.

  Implementation in blowfish-x86_64 uses 64bit rotations which are slow on P4,
  making blowfish-x86_64 slower than generic C implementation. Therefore
  blacklist P4.

  Patch adds x86_64 assembly implementation of blowfish. Two set of assembler
  functions are provided. First set is regular 'one-block at time'
  encrypt/decrypt functions. Second is 'four-block at time' functions that
  gain performance increase on out-of-order CPUs. Performance of 4-way
  functions should be equal to 1-way functions with in-order CPUs.

  Summary of the tcrypt benchmarks:

  Blowfish assembler vs blowfish C (256bit 8kb block ECB)
  encrypt: 2.2x speed
  decrypt: 2.3x speed

  Blowfish assembler vs blowfish C (256bit 8kb block CBC)
  encrypt: 1.12x speed
  decrypt: 2.5x speed

  Blowfish assembler vs blowfish C (256bit 8kb block CTR)
  encrypt: 2.5x speed
