The current mapping of memory controller indices is from physical index [1]
to logical index [2], as show below:
skx_dev->imc[pmc].mc_mapping = lmc
Since skx_dev->imc[] is an array of present memory controller instances,
mapping memory controller indices from logical index to physical index,
as show below, is more reasonable. This is also a preparatory step for
making skx_dev->imc[] a flexible array.
skx_dev->imc[lmc].mc_mapping = pmc
Both mappings are equivalent. No functional changes intended.
[1] Indices for memory controllers include both those present to the
OS and those disabled by BIOS.
[2] Indices for memory controllers present to the OS.

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.
