Len Brown 66f4305224 tools/power x86_energy_perf_policy.8: Emphasize preference for SW interfaces
This tool was originally written when Linux had no standard
interface for EPB, or HWP support.

Retain the capability to manage a system w/o any kernel PM support,
but prefer the standard kernel interfaces, when avaialble.

(not doing so led to a confusing conflict between a p-state limit
 request made via cpufreq and modified by the intel-pstate driver,
 versus the raw MSR write made by this utility)

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
