Sumeet Pawnikar 089aece01a powercap: RAPL: fix invalid initialization for pl4_supported field 
commit d05b5e0baf424c8c4b4709ac11f66ab726c8deaf upstream.

The current initialization of the struct x86_cpu_id via
pl4_support_ids[] is partial and wrong. It is initializing
"stepping" field with "X86_FEATURE_ANY" instead of "feature" field.

Use X86_MATCH_INTEL_FAM6_MODEL macro instead of initializing
each field of the struct x86_cpu_id for pl4_supported list of CPUs.
This X86_MATCH_INTEL_FAM6_MODEL macro internally uses another macro
X86_MATCH_VENDOR_FAM_MODEL_FEATURE for X86 based CPU matching with
appropriate initialized values.

[ Ricardo: I only kept TIGERLAKE in pl4_support_ids as only this model is

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.
