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
