From: Andi Kleen <ak@suse.de>
Add links for p4-clockmod driver in x86-64 cpufreq.
AK: Made it dependent on EMBEDDED because the driver is only
useful in some special situations and should be normally not used.

+ This adds the clock modulation driver for Intel Pentium 4 / XEON
+ processors. When enabled it will lower CPU temperature by skipping
+ clocks.
+
+ This driver should be only used in exceptional

+
+ For details, take a look at <file:Documentation/cpu-freq/>.
