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 pointer size when caam is used with AArch64 boot loader on
AArch32 kernel.
- Fix ahash state corruption in marvell driver.
- Fix buggy algif_aed tag handling.
- Prevent mcryptd from being used with incompatible algorithms which
can cause crashes"

crypto: mcryptd - Check mcryptd algorithm compatibility
crypto: algif_aead - fix AEAD tag memory handling
crypto: caam - fix pointer size for AArch64 boot loader, AArch32 kernel
crypto: marvell - Don't corrupt state of an STD req for re-stepped ahash
