Ingo Molnar 266d63a7d9 x86/cpufeature: Fix various quality problems in the <asm/cpu_device_hd.h> header
Thomas noticed that the new arch/x86/include/asm/cpu_device_id.h header is
a train-wreck that didn't incorporate review feedback like not using __u8
in kernel-only headers.

While at it also fix all the *other* problems this header has:

 - Use canonical names for the header guards. It's inexplicable why a non-standard
   guard was used.

 - Don't define the header guard to 1. Plus annotate the closing #endif as done
   absolutely every other header. Again, an inexplicable source of noise.

 - Move the kernel API calls provided by this header next to each other, there's
   absolutely no reason to have them spread apart in the header.

 - Align the INTEL_CPU_DESC() macro initializations vertically, this is easier to
   read and it's also the canonical style.

 - Actually name the macro arguments properly: instead of 'mod, step, rev',
   spell out 'model, stepping, revision' - it's not like we have a lack of
   characters in this header.

 - Actually make arguments macro-safe - again it's inexplicable why it wasn't
   done properly to begin with.

Quite amazing how many problems a 41 lines header can contain.

This kind of code quality is unacceptable, and it slipped through the
review net of 2 developers and 2 maintainers, including myself, until
Thomas noticed it. :-/

README

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.
