Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx: DMAENGINE: extend the control command to include an arg async_tx: trim dma_async_tx_descriptor in 'no channel switch' case DMAENGINE: DMA40 fix for allocation of logical channel 0 DMAENGINE: DMA40 support paused channel status dmaengine: mpc512x: Use resource_size DMA ENGINE: Do not reset 'private' of channel ioat: Remove duplicated devm_kzalloc() calls for ioatdma_device ioat3: disable cacheline-unaligned transfers for raid operations ioat2,3: convert to producer/consumer locking ioat: convert to circ_buf DMAENGINE: Support for ST-Ericssons DMA40 block v3 async_tx: use of kzalloc/kfree requires the include of slab.h dmaengine: provide helper for setting txstate DMAENGINE: generic channel status v2 DMAENGINE: generic slave control v2 dma: timb-dma: Update comment and fix compiler warning dma: Add timb-dma DMAENGINE: COH 901 318 fix bytesleft DMAENGINE: COH 901 318 rename confusing vars
