[ Upstream commit 4ec5d0231d ]
Add fields to struct intel_vsec_device, so that core module (which
creates aux bus devices) can pass private data to the client drivers.
For example there is one vsec device instance per CPU package. On a
multi package system, this private data can be used to pass the package
ID. This package id can be used by client drivers to change power
settings for a specific CPU package by targeting MMIO space of the
correct PCI device.

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.
