Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: skcipher - Use RNG interface instead of get_random_bytes
crypto: rng - RNG interface and implementation
crypto: api - Add fips_enable flag
crypto: skcipher - Move IV generators into their own modules
crypto: cryptomgr - Test ciphers using ECB
crypto: api - Use test infrastructure
crypto: cryptomgr - Add test infrastructure
crypto: tcrypt - Add alg_test interface
crypto: tcrypt - Abort and only log if there is an error
crypto: crc32c - Use Intel CRC32 instruction
crypto: tcrypt - Avoid using contiguous pages
crypto: api - Display larval objects properly
crypto: api - Export crypto_alg_lookup instead of __crypto_alg_lookup
crypto: Kconfig - Replace leading spaces with tabs
