Treat #PFs that occur during emulation of ENCLS as, wait for it, emulated
page faults. Practically speaking, this is a glorified nop as the
exception is never of the nested flavor, and it's extremely unlikely the
guest is relying on the side effect of an implicit INVLPG on the faulting
address.

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.
