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 3.12: - Added MODULE_SOFTDEP to allow pre-loading of modules. - Reinstated crct10dif driver using the module softdep feature. - Allow via rng driver to be auto-loaded. - Split large input data when necessary in nx. - Handle zero length messages correctly for GCM/XCBC in nx. - Handle SHA-2 chunks bigger than block size properly in nx. - Handle unaligned lengths in omap-aes. - Added SHA384/SHA512 to omap-sham. - Added OMAP5/AM43XX SHAM support. - Added OMAP4 TRNG support. - Misc fixes" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (66 commits) Reinstate "crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework" hwrng: via - Add MODULE_DEVICE_TABLE crypto: fcrypt - Fix bitoperation for compilation with clang crypto: nx - fix SHA-2 for chunks bigger than block size crypto: nx - fix GCM for zero length messages crypto: nx - fix XCBC for zero length messages crypto: nx - fix limits to sg lists for AES-CCM crypto: nx - fix limits to sg lists for AES-XCBC crypto: nx - fix limits to sg lists for AES-GCM crypto: nx - fix limits to sg lists for AES-CTR crypto: nx - fix limits to sg lists for AES-CBC crypto: nx - fix limits to sg lists for AES-ECB crypto: nx - add offset to nx_build_sg_lists() padata - Register hotcpu notifier after initialization padata - share code between CPU_ONLINE and CPU_DOWN_FAILED, same to CPU_DOWN_PREPARE and CPU_UP_CANCELED hwrng: omap - reorder OMAP TRNG driver code crypto: omap-sham - correct dma burst size crypto: omap-sham - Enable Polling mode if DMA fails crypto: tegra-aes - bitwise vs logical and crypto: sahara - checking the wrong variable ...
