    Pull slave-dmaengine changes from Vinod Koul:
     "This brings for slave dmaengine:
    
       - Change dma notification flag to DMA_COMPLETE from DMA_SUCCESS as
         dmaengine can only transfer and not verify validaty of dma
         transfers
    
       - Bunch of fixes across drivers:
    
          - cppi41 driver fixes from Daniel
    
          - 8 channel freescale dma engine support and updated bindings from
            Hongbo
    
          - msx-dma fixes and cleanup by Markus
    
       - DMAengine updates from Dan:
    
          - Bartlomiej and Dan finalized a rework of the dma address unmap
            implementation.
    
          - 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 [Walleij] for their review.
    
          - Testing the raid related corner cases of 1/ triggered bugs in
            the recently added 16-source operation support in the ioatdma
            driver.
    
          - Some minor fixes / cleanups to mv_xor and ioatdma"
