Intercept reads to invalid (non-existent) and write-only x2APIC registers
when configuring VMX's MSR bitmaps for x2APIC+APICv. When APICv is fully
enabled, Intel hardware doesn't validate the registers on RDMSR and
instead blindly retrieves data from the vAPIC page, i.e. it's software's
responsibility to intercept reads to non-existent and write-only MSRs.

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.
