Subject: [PATCH RESEND 0/2] Enable DMA driver for MIC X200 Coprocessor

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.
