Linux kernel source tree
9e2d0c3365
Hyper-V can run VMs at different privilege "levels" known as Virtual Trust Levels (VTL). Sometimes, it chooses to run two different VMs at different levels but they share some of their address space. In such setups VTL2 (higher level VM) has visibility of all of the VTL0 (level 0) memory space. When the CONFIG_X86_MPPARSE is enabled for VTL2, the VTL2 kernel performs a search within the low memory to locate MP tables. However, in systems where VTL0 manages the low memory and may contain valid tables, this scanning can result in incorrect MP table information being provided to the VTL2 kernel, mistakenly considering VTL0's MP table as its own Add noop functions to avoid MP parse scan by VTL2.

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.
