Most ARM(64) PCI/MSI domains mask and unmask in the parent domain after or before the PCI mask/unmask operation takes place. So there are more than a dozen of the same wrapper implementation all over the place. Don't make the same mistake with the new per device PCI/MSI domains and provide a new MSI feature flag, which lets the domain implementation enable this sequence in the PCI/MSI code.

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 reStructuredText 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.
