Assert that KVM doesn't set a SPTE to a value that could trigger an EPT Violation #VE on a non-MMIO SPTE, e.g. to help detect bugs even without KVM_INTEL_PROVE_VE enabled, and to help debug actual #VE failures. Note, this will run afoul of TDX support, which needs to reflect emulated MMIO accesses into the guest as #VEs (which was the whole point of adding EPT Violation #VE support in KVM). The obvious fix for that is to exempt MMIO SPTEs, but that's annoyingly difficult now that is_mmio_spte() relies on a per-VM value. However, resolving that conundrum is a future problem, whereas getting KVM_INTEL_PROVE_VE healthy is a current problem.

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 reStructuredText 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.
