Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto update from Herbert Xu: "Here is the crypto update for 3.9: - Added accelerated implementation of crc32 using pclmulqdq. - Added test vector for fcrypt. - Added support for OMAP4/AM33XX cipher and hash. - Fixed loose crypto_user input checks. - Misc fixes" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (43 commits) crypto: user - ensure user supplied strings are nul-terminated crypto: user - fix empty string test in report API crypto: user - fix info leaks in report API crypto: caam - Added property fsl,sec-era in SEC4.0 device tree binding. crypto: use ERR_CAST crypto: atmel-aes - adjust duplicate test crypto: crc32-pclmul - Kill warning on x86-32 crypto: x86/twofish - assembler clean-ups: use ENTRY/ENDPROC, localize jump labels crypto: x86/sha1 - assembler clean-ups: use ENTRY/ENDPROC crypto: x86/serpent - use ENTRY/ENDPROC for assember functions and localize jump targets crypto: x86/salsa20 - assembler cleanup, use ENTRY/ENDPROC for assember functions and rename ECRYPT_* to salsa20_* crypto: x86/ghash - assembler clean-up: use ENDPROC at end of assember functions crypto: x86/crc32c - assembler clean-up: use ENTRY/ENDPROC crypto: cast6-avx: use ENTRY()/ENDPROC() for assembler functions crypto: cast5-avx: use ENTRY()/ENDPROC() for assembler functions and localize jump targets crypto: camellia-x86_64/aes-ni: use ENTRY()/ENDPROC() for assembler functions and localize jump targets crypto: blowfish-x86_64: use ENTRY()/ENDPROC() for assembler functions and localize jump targets crypto: aesni-intel - add ENDPROC statements for assembler functions crypto: x86/aes - assembler clean-ups: use ENTRY/ENDPROC, localize jump targets crypto: testmgr - add test vector for fcrypt ...
