[ Upstream commit 2c3aedd9db6295619d21e50ad29efda614023bf1 ]
For Alderlake, the spec changes after the patch submitted and PC7/PC9
are removed.
Raptorlake and Meteorlake, which copy the Alderlake cstate PMU, also
don't have PC7/PC9.
Remove PC7/PC9 support for Alderlake/Raptorlake/Meteorlake.
Fixes: d0ca946bcf ("perf/x86/cstate: Add Alder Lake CPU support")

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.
