Jim Mattson f41ed21643 perf/x86/kvm: Add Cascade Lake Xeon steppings to isolation_ucodes[]
[ Upstream commit b3c3361fe325074d4144c29d46daae4fc5a268d5 ]

Cascade Lake Xeon parts have the same model number as Skylake Xeon
parts, so they are tagged with the intel_pebs_isolation
quirk. However, as with Skylake Xeon H0 stepping parts, the PEBS
isolation issue is fixed in all microcode versions.

Add the Cascade Lake Xeon steppings (5, 6, and 7) to the
isolation_ucodes[] table so that these parts benefit from Andi's
optimization in commit 9b545c04ab ("perf/x86/kvm: Avoid unnecessary
work in guest filtering").

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.
