+          This ACPI processor uploads Power Management information to the Xen hypervisor.
+
+	  To do that the driver parses the Power Management data and uploads said
+	  information to the Xen hypervisor. Then the Xen hypervisor can select the
+          proper Cx and Pxx states. It also registers itslef as the SMM so that
+          other drivers (such as ACPI cpufreq scaling driver) will not load.
+
+          To compile this driver as a module, choose M here: the
+          module will be called xen_acpi_processor  If you do not know what to choose,
+          select M here. If the CPUFREQ drivers are built in, select Y here.
