* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: Makefile - replace the use of <module>-objs with <module>-y crypto: hifn_795x - use cancel_delayed_work_sync() crypto: talitos - sparse check endian fixes crypto: talitos - fix checkpatch warning crypto: talitos - fix warning: 'alg' may be used uninitialized in this function crypto: cryptd - Adding the AEAD interface type support to cryptd crypto: n2_crypto - Niagara2 driver needs to depend upon CRYPTO_DES crypto: Kconfig - update broken web addresses crypto: omap-sham - Adjust DMA parameters crypto: fips - FIPS requires algorithm self-tests crypto: omap-aes - OMAP2/3 AES hw accelerator driver crypto: updates to enable omap aes padata: add missing __percpu markup in include/linux/padata.h MAINTAINERS: Add maintainer entries for padata/pcrypt
