Thomas Gleixner 6285aa5073 x86/msi: Provide msi message shadow structs
Create shadow structs with named bitfields for msi_msg data, address_lo and
address_hi and use them in the MSI message composer.

Provide a function to retrieve the destination ID. This could be inline,
but that'd create a circular header dependency.

[dwmw2: fix bitfields not all to be a union]

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.
