Boqun Feng 61bfd920ab PCI: hv: Move retarget related structures into tlfs header
Currently, retarget_msi_interrupt and other structures it relys on are
defined in pci-hyperv.c. However, those structures are actually defined
in Hypervisor Top-Level Functional Specification [1] and may be
different in sizes of fields or layout from architecture to
architecture. Let's move those definitions into x86's tlfs header file
to support virtual PCI on non-x86 architectures in the future. Note that
"__packed" attribute is added to these structures during the movement
for the same reason as we use the attribute for other TLFS structures in
the header file: make sure the structures meet the specification and
avoid anything unexpected from the compilers.

Additionally, rename struct retarget_msi_interrupt to
hv_retarget_msi_interrupt for the consistent naming convention, also
mirroring the name in TLFS.

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.
