+       The GRU is a hardware resource located in the system chipset. The GRU
+       contains memory that can be mmapped into the user address space. This memory is
+       used to communicate with the GRU to perform functions such as load/store,
+       scatter/gather, bcopy, AMOs, etc.  The GRU is directly accessed by user
+       instructions using user virtual addresses. GRU instructions (ex., bcopy) use
+       user virtual addresses for operands.
