IB: Add DMA mapping functions to allow device drivers to interpose The QLogic InfiniPath HCAs use programmed I/O instead of HW DMA. This patch allows a verbs device driver to interpose on DMA mapping function calls in order to avoid relying on bus_to_virt() and phys_to_virt() to undo the mappings created by dma_map_single(), dma_map_sg(), etc. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
