Composing the MSI message at the MSI chip level is wrong because the underlying parent domain is the one which knows how the message should be composed for the direct vector delivery or the interrupt remapping table entry. The interrupt remapping aware PCI/MSI chip does that already. Make the direct delivery chip do the same and move the composition of the direct delivery MSI message to the vector domain irq chip. This prepares for the upcoming device MSI support to avoid having architecture specific knowledge in the device MSI domain irq chips.

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.
