However, the physical map is altered to reside in 36-bit space, as follows.
Addresses are no longer mapped with VA == PA. All accesses from
software use the VA; the PA is only used for setting up windows
-and mappings. Note that the low 32 bits are the same as the VA above;
-only the top 4 bits vary:
+and mappings. Note that with the exception of PCI MEM and RIO, the low
+ 32 bits are the same as the VA above; only the top 4 bits vary:
