This is the first set of patches adding MIC X200 Coprocessor support. MIC PCIe card has a DMA controller with 2 channels: one for the host and the other one for the card. On host the channel is private and used only by the host driver to transfer data by the MIC virtio and SCIF drivers. Please refer to Documentation/mic/mic_overview.txt for a description about other MIC drivers. The patches have been compiled/validated against v4.5-rc2. Tested using dmatest module with module parameter "threads_per_chan=60". These patches have also been scanned by Fengguang Wu's 0-day infrastructure and no issues have been reported. In order for the device to function when IOMMU is enabled DMA alias quirk has to be enabled and it is being upstreamed on linux-pci (http://www.spinics.net/lists/linux-pci/msg48460.html). Resending this patch set with corrected recipient list.
