Several RDMA drivers, e.g. drivers/infiniband/hw/qib, use the CPU to
transfer data between memory and PCIe adapter. Because of performance
reasons it is important that the CPU cache is not flushed when such
drivers transfer data. Make this possible by allowing these drivers to
override the dma_map_
