+Description:   Dynamic addition and removal of CPU's.  This is not hotplug
+               removal, this is meant complete removal/addition of the CPU

+
+               probe: writes to this file will dynamically add a CPU to the
+               system.  Information written to the file to add CPU's is
+               architecture specific.
+
+               release: writes to this file dynamically remove a CPU from
+               the system.  Information writtento the file to remove CPU's
