Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto update from Herbert Xu: - Made x86 ablk_helper generic for ARM - Phase out chainiv in favour of eseqiv (affects IPsec) - Fixed aes-cbc IV corruption on s390 - Added constant-time crypto_memneq which replaces memcmp - Fixed aes-ctr in omap-aes - Added OMAP3 ROM RNG support - Add PRNG support for MSM SoC's - Add and use Job Ring API in caam - Misc fixes [ NOTE! This pull request was sent within the merge window, but Herbert has some questionable email sending setup that makes him public enemy #1 as far as gmail is concerned. So most of his emails seem to be trapped by gmail as spam, resulting in me not seeing them. - Linus ] * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (49 commits) crypto: s390 - Fix aes-cbc IV corruption crypto: omap-aes - Fix CTR mode counter length crypto: omap-sham - Add missing modalias padata: make the sequence counter an atomic_t crypto: caam - Modify the interface layers to use JR API's crypto: caam - Add API's to allocate/free Job Rings crypto: caam - Add Platform driver for Job Ring hwrng: msm - Add PRNG support for MSM SoC's ARM: DT: msm: Add Qualcomm's PRNG driver binding document crypto: skcipher - Use eseqiv even on UP machines crypto: talitos - Simplify key parsing crypto: picoxcell - Simplify and harden key parsing crypto: ixp4xx - Simplify and harden key parsing crypto: authencesn - Simplify key parsing crypto: authenc - Export key parsing helper function crypto: mv_cesa: remove deprecated IRQF_DISABLED hwrng: OMAP3 ROM Random Number Generator support crypto: sha256_ssse3 - also test for BMI2 crypto: mv_cesa - Remove redundant of_match_ptr crypto: sahara - Remove redundant of_match_ptr ...
