Thanks for accepting the patches Greg. The good news is that the 7 patches accepted build fine without patch 3 and the drivers load successfully. The bad news is that the MIC Coprocessors no longer boot without patch 3 since the host driver does not find any DMA channels. Reverting patch 5 titled "add dma support in host driver" with SHA d4ef098 allows the Coprocessors to boot again but accepting patch 3 instead is the cleanest solution here. Dan, please review patch 3 as we would really like it to get accepted before the 3.17 merge window opens.
