vmcs->apic_access_page is simply a token that the hypervisor puts into the PFN of a 4KB EPTE (or PTE if using shadow-paging) that triggers APIC-access VMExit or APIC virtualization logic whenever a CPU running in VMX non-root mode read/write from/to this PFN. As every write either triggers an APIC-access VMExit or write is performed on vmcs->virtual_apic_page, the PFN pointed to by vmcs->apic_access_page should never actually be touched by CPU. Therefore, there is no need to mark vmcs02->apic_access_page as dirty after unpin it on L2->L1 emulated VMExit or when L1 exit VMX operation.

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.
