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
+	  Say Y here to enable CPUfreq subsystem (including drivers)
+	  debugging. You will need to activate it via the kernel
+	  command line by passing
+	     cpufreq.debug=<value>
+
+	  To get <value>, add

+config CPU_FREQ_GOV_ONDEMAND
+	tristate "'ondemand' cpufreq policy governor"
+	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.
