Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "Here is the crypto update for 4.9: API: - The crypto engine code now supports hashes. Algorithms: - Allow keys >= 2048 bits in FIPS mode for RSA. Drivers: - Memory overwrite fix for vmx ghash. - Add support for building ARM sha1-neon in Thumb2 mode. - Reenable ARM ghash-ce code by adding import/export. - Reenable img-hash by adding import/export. - Add support for multiple cores in omap-aes. - Add little-endian support for sha1-powerpc. - Add Cavium HWRNG driver for ThunderX SoC" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (137 commits) crypto: caam - treat SGT address pointer as u64 crypto: ccp - Make syslog errors human-readable crypto: ccp - clean up data structure crypto: vmx - Ensure ghash-generic is enabled crypto: testmgr - add guard to dst buffer for ahash_export crypto: caam - Unmap region obtained by of_iomap crypto: sha1-powerpc - little-endian support crypto: gcm - Fix IV buffer size in crypto_gcm_setkey crypto: vmx - Fix memory corruption caused by p8_ghash crypto: ghash-generic - move common definitions to a new header file crypto: caam - fix sg dump hwrng: omap - Only fail if pm_runtime_get_sync returns < 0 crypto: omap-sham - shrink the internal buffer size crypto: omap-sham - add support for export/import crypto: omap-sham - convert driver logic to use sgs for data xmit crypto: omap-sham - change the DMA threshold value to a define crypto: omap-sham - add support functions for sg based data handling crypto: omap-sham - rename sgl to sgl_tmp for deprecation crypto: omap-sham - align algorithms on word offset crypto: omap-sham - add context export/import stubs ...
