+*               needed by the MTRR module. These functions may be included
+*               directly for native ring 0 device drivers, or they may
+*               be calls down to a ring 0 helper device driver where
+*               appropriate (or the entire MTRR module may be located in
+*               the device driver if the device driver is 32-bit).
