Merge commit 'dmaengine-3.13-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/dmaengine
Pull dmaengine changes from Dan 1/ Bartlomiej and Dan finalized a rework of the dma address unmap implementation. 2/ In the course of testing 1/ a collection of enhancements to dmatest fell out. Notably basic performance statistics, and fixed / enhanced test control through new module parameters 'run', 'wait', 'noverify', and 'verbose'. Thanks to Andriy and Linus for their review. 3/ Testing the raid related corner cases of 1/ triggered bugs in the recently added 16-source operation support in the ioatdma driver. 4/ Some minor fixes / cleanups to mv_xor and ioatdma. Conflicts: drivers/dma/dmatest.c Signed-off-by: Vinod Koul <vinod.koul@intel.com>
