- use spin_lock_bh() is the right way to use async_tx api,
dma_run_dependencies() should not be protected by spin_lock_irqsave();
- use spin_lock_bh to instead of spin_lock_irqsave for improving performance,
There is not any place to access descriptor queues in fsl-dma ISR except

Move the function fsldma_cleanup_descriptor() and fsl_chan_xfer_ld_queue()
ahead of its invoke function for avoiding redundant definition.

Fix the potential risk when enable config NET_DMA and ASYNC_TX.
Async_tx is lack of support in current release process of dma descriptor,
all descriptors will be released whatever is acked or no-acked by async_tx,
so there is a potential race condition when dma engine is uesd by o

Delete attribute DMA_INTERRUPT because fsl-dma doesn't support this function,
exception will be thrown if talitos is used to offload xor at the same time.

Hi,
The following 7 patches enabling fsl-dma and talitos offload raid
operations for improving raid performance and balancing CPU load.
Write performance will be improved by 25-30% tested by iozone.
Write performance is improved about 2% after using spin_lock_bh replace
spin_lock_irqsave.

Expose Talitos's XOR functionality to be used for RAID parity
calculation via the Async_tx layer.
