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
