mainlining shenanigans
cb0f722aff
When the 5-level page table CPU flag is set in the host, but the guest has CR4.LA57=0 (including the case of a 32-bit guest), the top level of the shadow NPT page tables will be fixed, consisting of one pointer to a lower-level table and 511 non-present entries. Extend the existing code that creates the fixed PML4 or PDP table, to provide a fixed PML5 table if needed. This is not needed on EPT because the number of layers in the tables is specified in the EPTP instead of depending on the host CR4.

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.
