Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx: (24 commits) I/OAT: I/OAT version 3.0 support I/OAT: tcp_dma_copybreak default value dependent on I/OAT version I/OAT: Add watchdog/reset functionality to ioatdma iop_adma: cleanup iop_chan_xor_slot_count iop_adma: document how to calculate the minimum descriptor pool size iop_adma: directly reclaim descriptors on allocation failure async_tx: make async_tx_test_ack a boolean routine async_tx: remove depend_tx from async_tx_sync_epilog async_tx: export async_tx_quiesce async_tx: fix handling of the "out of descriptor" condition in async_xor async_tx: ensure the xor destination buffer remains dma-mapped async_tx: list_for_each_entry_rcu() cleanup dmaengine: Driver for the Synopsys DesignWare DMA controller dmaengine: Add slave DMA interface dmaengine: add DMA_COMPL_SKIP_{SRC,DEST}_UNMAP flags to control dma unmap dmaengine: Add dma_client parameter to device_alloc_chan_resources dmatest: Simple DMA memcpy test client dmaengine: DMA engine driver for Marvell XOR engine iop-adma: fix platform driver hotplug/coldplug dmaengine: track the number of clients using a channel ... Fixed up conflict in drivers/dca/dca-sysfs.c manually
