Pull crypto fix from Herbert Xu:
 "This fixes a bug in cavium/nitrox where the callback is invoked prior
  to the DMA unmap"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: cavium/nitrox - Invoke callback after DMA unmap

In process_response_list() invoke the callback handler after unmapping
the DMA buffers. It ensures DMA data is synced form device to cpu
before the client code access the data from callback handler.

Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:
   - Zero-length DMA mapping in caam
   - Invalidly mapping stack memory for DMA in talitos
   - Use after free in cavium/nitrox
   - Key parsing in authenc
   - Undefined shift in sm3
   - Bogus completion call in authencesn
   - SHA support detection in caam"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: sm3 - fix undefined shift by >= width of value
  crypto: talitos - fix ablkcipher for CONFIG_VMAP_STACK
  crypto: talitos - reorder code in talitos_edesc_alloc()
  crypto: adiantum - initialize crypto_spawn::inst
  crypto: cavium/nitrox - Use after free in process_response_list()
  crypto: authencesn - Avoid twice completion call in decrypt path
  crypto: caam - fix SHA support detection
  crypto: caam - fix zero-length buffer DMA mapping
  crypto: ccree - convert to use crypto_authenc_extractkeys()
  crypto: bcm - convert to use crypto_authenc_extractkeys()
  crypto: authenc - fix parsing key with misaligned rta_len

We free "sr" and then dereference it on the next line.

We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.
