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: ack to flags: make use of the unused bits in the 'ack' field iop-adma: remove the workaround for missed interrupts on iop3xx async_tx: kill ->device_dependency_added async_tx: fix multiple dependency submission fsldma: Split the MPC83xx event from MPC85xx and refine irq codes. fsldma: Remove CONFIG_FSL_DMA_SELFTEST, keep fsl_dma_self_test() running always.
