Linus Torvalds f390b7bffd Urgent power management fixes for 4.18
- Use ACPI FADT preferred PM Profile to distinguish Skylake
    desktop processors from some server ones with the same model
    number in order to limit the scope of the recent IO-wait boost
    optimization to servers, as intended (Srinivas Pandruvada).
 
  - Fix several issues in the turbostat utility:
    * Fix the -S option on 1-CPU systems (Len Brown).
    * Fix computations using incorrect processor core counts (Artem
      Bityutskiy).
    * Fix the x2apic debug message (Len Brown).
    * Fix logical node enumeration to allow for non-sequential
      physical nodes (Prarit Bhargava).
    * Fix reported family on modern AMD processors (Calvin Walton).
    * Clarify the RAPL column information in the man page (Len Brown).

Pull power management fixes from Rafael Wysocki:
 "These fix the scope of a recent intel_pstate driver optimization used
  incorrectly on some systems due to processor identification ambiguity
  and fix a few issues in the turbostat utility, including three recent
  regressions.

  Specifics:

   - Use ACPI FADT preferred PM Profile to distinguish Skylake desktop
     processors from some server ones with the same model number in
     order to limit the scope of the recent IO-wait boost optimization
     to servers, as intended (Srinivas Pandruvada).

   - Fix several issues in the turbostat utility:
      * Fix the -S option on 1-CPU systems (Len Brown).
      * Fix computations using incorrect processor core counts (Artem
        Bityutskiy).
      * Fix the x2apic debug message (Len Brown).
      * Fix logical node enumeration to allow for non-sequential
        physical nodes (Prarit Bhargava).
      * Fix reported family on modern AMD processors (Calvin Walton).

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
