5657933dbb treewide: Move dma_ops from struct dev_archdata into struct device 
Some but not all architectures provide set_dma_ops(). Move dma_ops
from struct dev_archdata into struct device such that it becomes
possible on all architectures to configure dma_ops per device.

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. This patch
has been generated as follows:

5ec4ca6adb misc: mic: SCIF Hardware Bus 
The SCIF hardware bus abstracts the low level hardware driver details
like interrupts and mapping remote memory so that the same SCIF driver
can work without any changes with the MIC host or card driver as long
as the hardware bus operations are implemented. The SCIF hardware
device is registered by the host and card drivers on the SCIF hardware
bus resulting in probing the SCIF driver.
