-          APM is a BIOS specification for saving power using several different
-          techniques. This is mostly useful for battery powered laptops with
-          APM compliant BIOSes. If you say Y here, the system time will be
-          reset after a RESUME operation, the /proc/apm device will provide
-          battery status information, and user-space programs will receive
-          notification of APM "events" (e.g. battery status change).
-
-          In order to use APM, you will need supporting software. For location
-          and more information, read <file:Documentation/pm.txt> and the
-          Battery Powered Linux mini-HOWTO, available from
-          <http://www.tldp.org/docs.html#howto>.
-
-          This driver does not spin down disk drives (see the hdparm(8)
-          manpage ("man 8 hdparm") for that), and it doesn't turn off
-          VESA-compliant "green" monitors.
-
-          Generally, if you don't have a battery in your machine, there isn't
-          much point in using this driver and you should say N. If you get
-          random kernel OOPSes or reboots that don't seem to be related to
-          anything, try disabling/enabling this option (or disabling/enabling
-          APM in your BIOS).

-          APM is a BIOS specification for saving power using several different
-          techniques. This is mostly useful for battery powered systems with
-          APM compliant BIOSes. If you say Y here, the system time will be
-          reset after a RESUME operation, the /proc/apm device will provide
-          battery status information, and user-space programs will receive
-          notification of APM "events" (e.g. battery status change).
-
-          In order to use APM, you will need supporting software. For location
-          and more information, read <file:Documentation/pm.txt> and the
-          Battery Powered Linux mini-HOWTO, available from
-          <http://www.tldp.org/docs.html#howto>.
-
-          This driver does not spin down disk drives (see the hdparm(8)
-          manpage ("man 8 hdparm") for that), and it doesn't turn off
-          VESA-compliant "green" monitors.
-
-          Generally, if you don't have a battery in your machine, there isn't
-          much point in using this driver and you should say N. If you get
-          random kernel OOPSes or reboots that don't seem to be related to
-          anything, try disabling/enabling this option (or disabling/enabling
-          APM in your BIOS).

+ * The HV supports 256 plugs per thread, assigned as {0..255}, for a total

+ * implementation equates HV plug value to Linux virq value, constrains each
+ * interrupt to have a system wide unique plug number, and limits the range
+ * of the plug values to map into the first dword of the bitmaps.  This

+ * purpose.  Current, the first 512 bytes and the last 256 bytes of
+ * memory are used.  Right now I am conservative and only use the
+ * memory that can never be used for microcode.  If there are
+ * applications that require more DP ram, we can expand the boundaries

+          suited for restricted-space environments, in which it also
+          demonstrates excellent performance. Rijndael's operations are
+          among the easiest to defend against power and timing attacks.
