On 32bit there is no APIC implementing the acpi_madt_oem_check() except XEN PV, but that does not matter at all. generic_apic_probe() runs before ACPI tables are parsed. This selects the XEN APIC if there is no command line override because the XEN APIC driver is the first to be probed. If there is a command line override then the XEN PV driver won't be selected in the MADT OEM check either. As there is no other MADT check implemented for 32bit APICs, this whole excercise is a NOOP and can be removed.

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.
