Update the intel_idle driver to get the C-states information from ACPI _CST in some cases in which the processor is known to the driver, as long as that information is available and the new use_acpi flag is set in the profile of the processor in question. In the cases when there is a specific table of C-states for the given processor in the driver, that table is used as the primary source of information on the available C-states, but if ACPI _CST is present, the C-states that are not listed by it will not be enabled by default (they still can be enabled later by user space via sysfs, though). The new CPUIDLE_FLAG_ALWAYS_ENABLE flag can be used for marking C-states that should be enabled by default even if they are not listed by ACPI _CST. Signed-off-by: Rafael J.

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 Restructured Text 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.
