Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Introduce crypto_shash_tfm_digest() and use it wherever possible. - Fix use-after-free and race in crypto_spawn_alg. - Add support for parallel and batch requests to crypto_engine. Algorithms: - Update jitter RNG for SP800-90B compliance. - Always use jitter RNG as seed in drbg. Drivers: - Add Arm CryptoCell driver cctrng. - Add support for SEV-ES to the PSP driver in ccp" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (114 commits) crypto: hisilicon - fix driver compatibility issue with different versions of devices crypto: engine - do not requeue in case of fatal error crypto: cavium/nitrox - Fix a typo in a comment crypto: hisilicon/qm - change debugfs file name from qm_regs to regs crypto: hisilicon/qm - add DebugFS for xQC and xQE dump crypto: hisilicon/zip - add debugfs for Hisilicon ZIP crypto: hisilicon/hpre - add debugfs for Hisilicon HPRE crypto: hisilicon/sec2 - add debugfs for Hisilicon SEC crypto: hisilicon/qm - add debugfs to the QM state machine crypto: hisilicon/qm - add debugfs for QM crypto: stm32/crc32 - protect from concurrent accesses crypto: stm32/crc32 - don't sleep in runtime pm crypto: stm32/crc32 - fix multi-instance crypto: stm32/crc32 - fix run-time self test issue. crypto: stm32/crc32 - fix ext4 chksum BUG_ON() crypto: hisilicon/zip - Use temporary sqe when doing work crypto: hisilicon - add device error report through abnormal irq crypto: hisilicon - remove codes of directly report device errors through MSI crypto: hisilicon - QM memory management optimization crypto: hisilicon - unify initial value assignment into QM ...
