Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+config CPU_FREQ
+ bool "CPU Frequency scaling"
+ help
+ CPU Frequency scaling allows you to change the clock speed of
+ CPUs on the fly. This is a nice method to save power, because
+ the lower the CPU clock speed, the less power the CPU consumes.
+
+ Note that this driver doesn't automatically change the CPU
+ clock speed, you need to either enable a dynamic cpufreq governor
+ (see below) after boot, or use a userspace tool.
+
+ For details, take a look at <file:Documentation/cpu-freq>.
+
+ If in doubt, say N.

+ help
+ 'ondemand' - This driver adds a dynamic cpufreq policy governor.
+ The governor does a periodic polling and
+ changes frequency based on the CPU utilization.
+ The support for this governor depends on CPU capability to
+ do fast frequency switching (i.e, very low latency frequency
+ transitions).
+
+ For details, take a look at linux/Documentation/cpu-freq.
+
+ If in doubt, say N.
