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.

Regards,
Dan
