Memory errors could be printed with incorrect row values since the DIMM size has outgrown the 16 bit row field in the CPER structure. UEFI Specification Version 2.8 has increased the size of row by allowing it to use the first 2 bits from a previously reserved space within the structure. When needed, add the extension bits to the row value printed. Based on UEFI 2.8 Table 299.

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.
