Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto update from Herbert Xu:
 - add multibuffer infrastructure (single_task_running scheduler helper,
   OKed by Peter on lkml.
 - add SHA1 multibuffer implementation for AVX2.
 - reenable "by8" AVX CTR optimisation after fixing counter overflow.
 - add APM X-Gene SoC RNG support.
 - SHA256/SHA512 now handles unaligned input correctly.
 - set lz4 decompressed length correctly.
 - fix algif socket buffer allocation failure for 64K page machines.
 - misc fixes
