Use vm->max_gfn to compute the highest gpa in vmx_apic_access_test, and blindly trust that the highest gfn/gpa will be well above the memory carved out for memslot0. The existing check is beyond paranoid; KVM doesn't support CPUs with host.MAXPHYADDR < 32, and the selftests are all kinds of hosed if memslot0 overlaps the local xAPIC, which resides above "lower" (below 4gb) DRAM.

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.
