Now that interrupt remapping sets the irqdomain pointer when a PCI device is added it's possible to store the default irq domain in the device struct in pcibios_add_device(). If the bus to which a device is connected has an irq domain associated then this domain is used otherwise the default domain (PCI/MSI native or XEN PCI/MSI) is used. Using the bus domain ensures that special MSI bus domains like VMD work. This makes XEN and the non-remapped native case work solely based on the irq domain pointer in struct device for PCI/MSI and allows to remove the arch fallback and make most of the x86_msi ops private to XEN in the next steps.

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.
