+ *
+ * ForceClear sets the permanent disable and deactivated flags to their default
+ * value of TRUE.  The specs say nothing about STCLEAR flags, so they should be
+ * left alone.  This test checks that both flags may be reset without a reboot,
+ * resulting in a fully enabled and activated TPM.  (We know that because
+ * ForceClear requires that the TPM be enabled and activated to run.)
