In order to simplify backports, I resorted to an older version of the
microcode revision checking which didn't pull in the whole struct
x86_cpu_id matching machinery.
My simpler method, however, forgot to add the extended CPU model to the
patch revision, which lead to mismatches when determining whether TSA
mitigation support is present.
So add that forgotten extended model.
This is a stable-only fix and the preference is to do it this way
because it is a lot simpler. Also, the Fixes: tag below points to the
respective stable patch.

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.
