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 a number of regressions in the marvell cesa driver caused by the chaining work, and a regression in lib/mpi that leads to a GFP_KERNEL allocation with preemption disabled" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: marvell - Don't copy IV vectors from the _process op for ciphers lib/mpi: Fix SG miter leak crypto: marvell - Update cache with input sg only when it is unmapped crypto: marvell - Don't chain at DMA level when backlog is disabled crypto: marvell - Fix memory leaks in TDMA chain for cipher requests
