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.
