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: - oversize stack frames on mn10300 in sha3-generic - warning on old compilers in sha3-generic - API error in sun4i_ss_prng - potential dead-lock in sun4i_ss_prng - null-pointer dereference in sha512-mb - endless loop when DECO acquire fails in caam - kernel oops when hashing empty message in talitos" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: sun4i_ss_prng - convert lock to _bh in sun4i_ss_prng_generate crypto: sun4i_ss_prng - fix return value of sun4i_ss_prng_generate crypto: caam - fix endless loop when DECO acquire fails crypto: sha3-generic - Use __optimize to support old compilers compiler-gcc.h: __nostackprotector needs gcc-4.4 and up compiler-gcc.h: Introduce __optimize function attribute crypto: sha3-generic - deal with oversize stack frames crypto: talitos - fix Kernel Oops on hashing an empty file crypto: sha512-mb - initialize pending lengths correctly
