++DMA_ATTR_PRIVILEGED
++-------------------
++
++Some advanced peripherals such as remote processors and GPUs perform
++accesses to DMA buffers in both privileged "supervisor" and unprivileged
++"user" modes. This attribute is used to indicate to the DMA-mapping
++subsystem that the buffer is fully accessible at the elevated privilege
++level (and ideally inaccessible or at least read-only at the
++lesser-privileged levels).
