Bart Van Assche	5299709d0a	treewide: Constify most dma_map_ops structures ... Most dma_map_ops structures are never modified. Constify these structures such that these can be write-protected.

Ashutosh Dixit	d411e79391	misc: mic: Remove COSM functionality from the MIC card driver ... Since card side COSM functionality, to trigger MIC device shutdowns and communicate shutdown status to the host, is now moved into a separate COSM client driver, this patch removes this functionality from the base MIC card driver. The mic_bus driver is also updated to use the device index provided by COSM rather than maintain its own device index.

Sudeep Dutt	726526c355	misc: mic: add a bus driver for virtual MIC devices ... This MIC virtual bus driver takes the responsibility of creating all the virtual devices connected to the PCIe device on the host and the platform device on the card. The MIC bus hardware operations provide a way to abstract certain hardware details from the base physical devices. Examples of devices added on the MIC virtual bus include host DMA and card DMA. This abstraction enables using a common DMA driver on host and card.
