Enabling async page faults is nonsensical if paging is disabled, but it is allowed because CR0.PG=0 does not clear the async page fault MSR. Just ignore them and only use the artificial halt state, similar to what happens in guest mode if async #PF vmexits are disabled. Given the increasingly complex logic, and the nicer code if the new "if" is placed last, opportunistically change the "||" into a chain of "if (...) return false" statements.

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.
