Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"The last push broke algif_hash for all shash implementations, so this
is a follow-up to fix that.
This also fixes a problem in the crypto scatterwalk that triggers a
BUG_ON with certain debugging options due to the new vmalloced-stack
code"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: scatterwalk - Remove unnecessary aliasing check in map_and_copy
crypto: algif_hash - Fix result clobbering in recvmsg
