Yazen Ghannam 23d02ee1d4 x86/cpu/amd: Set __max_die_per_package on AMD 
commit 76e2fc63ca upstream.

Set the maximum DIE per package variable on AMD using the
NodesPerProcessor topology value. This will be used by RAPL, among
others, to determine the maximum number of DIEs on the system in order
to do per-DIE manipulations.

 [ bp: Productize into a proper patch. ]

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.
