While all drivers should explicitly indicate the DMA capability
(e.g. 32 or 64 bit) of the PCI bus master, devices with more than
32-bit bus master capability for streaming data need the driver
to "register" this capability by calling pci_set_dma_mask() with
to "register" this capability by calling dma_set_mask() with
appropriate parameters. In general this allows more efficient DMA
on systems where System RAM exists above 4G _physical_ address.
Drivers for all PCI-X and PCIe compliant devices must call
set_dma_mask() as they are 64-bit DMA devices.
dma_set_mask() as they are 64-bit DMA devices.
Similarly, drivers must also "register" this capability if the device
can directly address "coherent memory" in System RAM above 4G physical
