Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto update from Herbert Xu:
 "API:
   - Add support for AEAD in simd
   - Add fuzz testing to testmgr
   - Add panic_on_fail module parameter to testmgr
   - Use per-CPU struct instead multiple variables in scompress
   - Change verify API for akcipher

  Algorithms:
   - Convert x86 AEAD algorithms over to simd
   - Forbid 2-key 3DES in FIPS mode
   - Add EC-RDSA (GOST 34.10) algorithm

  Drivers:
   - Set output IV with ctr-aes in crypto4xx
   - Set output IV in rockchip
   - Fix potential length overflow with hashing in sun4i-ss
   - Fix computation error with ctr in vmx
   - Add SM4 protected keys support in ccree
   - Remove long-broken mxc-scc driver
   - Add rfc4106(gcm(aes)) cipher support in cavium/nitrox"
