Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
API:
- algif_hash needs to wait for init operations to complete.
- The has_key setting for shash was always true.
Algorithms:
- Add missing selections of CRYPTO_HASH.
- Fix pkcs7 authentication.
Drivers:
- Fix stack alignment bug in chacha20-ssse3.
- Fix performance regression in caam due to incorrect setting.
- Fix potential compile-only build failure of stm32"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: atmel-aes - remove calls of clk_prepare() from atomic contexts
crypto: algif_hash - wait for crypto_ahash_init() to complete
crypto: shash - Fix has_key setting
hwrng: stm32 - Fix dependencies for !HAS_IOMEM archs
crypto: ghash,poly1305 - select CRYPTO_HASH where needed
crypto: chacha20-ssse3 - Align stack pointer to 64 bytes
PKCS#7: Don't require SpcSpOpusInfo in Authenticode pkcs7 signatures
crypto: caam - make write transactions bufferable on PPC platforms
