Borislav Petkov deedec0a15 x86/cpu: Fix the AMD Fam 17h, Fam 19h, Zen2 and Zen4 MSR enumerations
The comments introduced in <asm/msr-index.h> in the merge conflict fixup in:

  8f4156d587 ("Merge branch 'x86/urgent' into perf/core, to resolve conflict")

... aren't right: AMD naming schemes are more complex than implied,
family 0x17 is Zen1 and 2, family 0x19 is spread around Zen 3 and 4.

So there's indeed four separate MSR namespaces for:

  MSR_F17H_
  MSR_F19H_
  MSR_ZEN2_
  MSR_ZEN4_

... and the namespaces cannot be merged.

Fix it up. No change in functionality.

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.
