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: - fix chacha20 crash on zero-length input due to unset IV - fix potential race conditions in mcryptd with spinlock - only wait once at top of algif recvmsg to avoid inconsistencies - fix potential use-after-free in algif_aead/algif_skcipher" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: af_alg - fix race accessing cipher request crypto: mcryptd - protect the per-CPU queue with a lock crypto: af_alg - wait for data at beginning of recvmsg crypto: skcipher - set walk.iv for zero-length inputs
