It is only possible to share the APIC access page between L1 and L2 if they also share the virtual-APIC page. If L2 has its own virtual-APIC page, then MMIO accesses to L1's TPR from L2 will access L2's TPR instead. Moreover, L1's local APIC has to be in xAPIC mode, which is another condition that hasn't been checked.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
