When CPUs come online the MSC's original configuration should be restored. Add struct mpam_config to hold the configuration. For each component, this has a bitmap of features that have been changed from the reset values. The mpam_config is also used on RIS reset where all bits are set to ensure all features are reset. Once the maximum partid is known, allocate a configuration array for each component, and reprogram each RIS configuration from this.

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.
