Reinette Chatre 521348b011 x86/intel_rdt: Introduce utility to obtain CDP peer
Introduce a utility that, when provided with a RDT resource and an
instance of this RDT resource (a RDT domain), would return pointers to
the RDT resource and RDT domain that share the same hardware. This is
specific to the CDP resources that share the same hardware.

For example, if a pointer to the RDT_RESOURCE_L2DATA resource (struct
rdt_resource) and a pointer to an instance of this resource (struct
rdt_domain) is provided, then it will return a pointer to the
RDT_RESOURCE_L2CODE resource as well as the specific instance that
shares the same hardware as the provided rdt_domain.

This utility is created in support of the "exclusive" resource group
mode where overlap of resource allocation between resource groups need
to be avoided. The overlap test need to consider not just the matching
resources, but also the resources that share the same hardware.

Temporarily mark it as unused in support of patch testing to avoid
compile warnings until it is used.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
