Pull crypto fixes from Herbert Xu: "This push fixes a memory corruption issue in caam, as well as reverting the new optimised crct10dif implementation as it breaks boot on initrd systems. Hopefully crct10dif will be reinstated once the supporting code is added so that it doesn't break boot" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: Revert "crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework" crypto: caam - Fixed the memory out of bound overwrite issue

Drivers may select this option to force specific constant

(error correction capability). Those specific values must

be set by declaring default values for symbols BCH_CONST_M

Doing so will enable extra compiler optimizations,
