 "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"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: algif_aead - fix uninitialized variable warning
  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
  crypto: marvell - Don't copy hash operation twice into the SRAM
