Thomas Gleixner 69460b1ed6 x86/cpu: Add consistent CPU match macros
commit 20d437447c0089cda46c683db219d3b4e2cde40e upstream.

Finding all places which build x86_cpu_id match tables is tedious and the
logic is hidden in lots of differently named macro wrappers.

Most of these initializer macros use plain C89 initializers which rely on
the ordering of the struct members. So new members could only be added at
the end of the struct, but that's ugly as hell and C99 initializers are
really the right thing to use.

Provide a set of macros which:

  - Have a proper naming scheme, starting with X86_MATCH_

  - Use C99 initializers

The set of provided macros are all subsets of the base macro

    X86_MATCH_VENDOR_FAM_MODEL_FEATURE()

which allows to supply all possible selection criteria:

      vendor, family, model, feature

The other macros shorten this to avoid typing all arguments when they are
not needed and would require one of the _ANY constants. They have been
created due to the requirements of the existing usage sites.

Also add a few model constants for Centaur CPUs and QUARK.

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.
