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
