When AVIC, and thus IPI virtualization on AMD, is enabled, the CPU will virtualize ICR writes. Unfortunately, the CPU doesn't do a very good job, as it fails to clear the BUSY bit and also allows writing ICR2[23:0], despite them being "RESERVED MBZ". Account for the quirky behavior in the xapic_state test to avoid failures in a configuration that likely has no hope of ever being enabled in production.

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.
