Qiuxu Zhuo 36d640372f EDAC/skx: Fix overflows on the DRAM row address mapping arrays 
[ Upstream commit 71b1e3ba3f ]

The current DRAM row address mapping arrays skx_{open,close}_row[]
only support ranks with sizes up to 16G. Decoding a rank address
to a DRAM row address for a 32G rank by using either one of the
above arrays by the skx_edac driver, will result in an overflow on
the array.

For a 32G rank, the most significant DRAM row address bit (the
bit17) is mapped from the bit34 of the rank address. Add this new
mapping item to both arrays to fix the overflow issue.

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.
