There is a selftest that checks for an (expected) error when an invalid AR is specified, but not one that exercises the AR path. Add a simple test that mirrors the vanilla write/read test while providing an AR. An AR that contains zero will direct the CPU to use the primary address space normally used anyway. AR[1] is selected for this test because the host AR[1] is usually non-zero, and KVM needs to correctly swap those values.

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.
