Intel CPUs have been using Family 6 for a while. The Family-model checks in the coretemp driver implicitly assume Family 6. With the upcoming Family 18 and 19 models, some of these checks fall apart. While reading the temperature target MSR, cpu_has_tjmax() performs model checks only to determine if a device warning should be printed. Instead of expanding the checks, get rid of the function and print the warning once unconditionally if the MSR read fails. The checks aren't worth preventing a single line warning to dmesg. Update the rest of the x86_model checks with VFM ones to make them more robust. This automatically covers the upcoming Family 18 and 19 as well as any future extended families. Add a code comment to reflect that none of the CPUs in Family 5 or Family 15 set X86_FEATURE_DTHERM. The VFM checks do not impact these CPUs since the driver does not load on them.

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 reStructuredText 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.
