+          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.
