Some additional commits [1] have been appended to this tree since the
initial pull request [2].  The new commits are either simple cleanups
(iop-adma), fixes confirmed to address known issues (xor-unmap,
xor-out-of-descriptors, ioat-watchdog), or new hardware support
(ioat-v3).  Here is the description from the previous request: 

> This update brings two new drivers, an expansion of the dmaengine
> infrastructure to enable device-to-memory dma, as well as a mechanism
> for exclusive client-channel associations.  Also notable for developers
> is the addition of the dmatest client for dmaengine driver validation.
> 
> One api extension was made to allow intelligent clients more control
> over dma-unmapping.  There is a follow on patch brewing to use this
> capability to fix a case where xor buffers are unmapped too early.  It
> is not an urgent concern since the only xor offload engine drivers in
> mainline are for configurations where dma-unmap is a nop.

Thanks,
Dan
