Use __kvm_faultin_page() get the APIC access page so that KVM can precisely release the refcounted page, i.e. to remove yet another user of kvm_pfn_to_refcounted_page(). While the path isn't handling a guest page fault, the semantics are effectively the same; KVM just happens to be mapping the pfn into a VMCS field instead of a secondary MMU.

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.
