Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 

Pull crypto fixes from Herbert Xu:

 - Check for the right CPU feature bit in sm4-ce on arm64.

 - Fix scatterwalk WARN_ON in aes-gcm-ce on arm64.

 - Fix unaligned fault in aesni on x86.

 - Fix potential NULL pointer dereference on exit in chtls.

 - Fix DMA mapping direction for RSA in caam.

 - Fix error path return value for xts setkey in caam.

 - Fix address endianness when DMA unmapping in caam.

 - Fix sleep-in-atomic in vmx.

 - Fix command corruption when queue is full in cavium/nitrox.

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: cavium/nitrox - fix for command corruption in queue full case with backlog submissions.
  crypto: vmx - Fix sleep-in-atomic bugs
  crypto: arm64/aes-gcm-ce - fix scatterwalk API violation
  crypto: aesni - Use unaligned loads from gcm_context_data
  crypto: chtls - fix null dereference chtls_free_uld()
  crypto: arm64/sm4-ce - check for the right CPU feature bit
  crypto: caam - fix DMA mapping direction for RSA forms 2 & 3
  crypto: caam/qi - fix error path in xts setkey
  crypto: caam/jr - fix descriptor DMA unmapping
