> Previously, in order to use the power library, it was necessary
> for the user to disable the intel_pstate driver by adding
> “intel_pstate=disable” to the kernel command line for the system,
> which causes the acpi_cpufreq driver to be loaded in its place.
> This patch adds the ability for the power library use the intel-pstate
> driver.
> It adds a new suite of functions behind the current power library API,
> and will seamlessly set up the user facing API function pointers to
> the relevant functions depending on whether the system is running with
> acpi_cpufreq kernel driver, intel_pstate kernel driver or in a guest,
> using kvm. The library API and ABI is unchanged.
