[PATCH v2 0/4] Raid: enable talitos xor offload for improving performance

The following 4 patches enabling fsl-dma and talitos offload raid
operations for improving raid performance and balancing CPU load.

Write performance will be improved by 40% tested by iozone. CPU load
will be reduced by 8%.

Changes in v2:
	- rebase onto cryptodev tree
	- split the patch 3/4 up to 3 independent patches
	- remove the patch 4/4, the fix is not for cryptodev tree

Qiang Liu (4):
      Talitos: Support for async_tx XOR offload
      fsl-dma: remove attribute DMA_INTERRUPT of dmaengine
      fsl-dma: change the release process of dma descriptor
      fsl-dma: use spin_lock_bh to instead of spin_lock_irqsave
