Add a VMX specific test to verify that KVM doesn't explode if userspace attempts KVM_RUN when emulation is required with a pending exception. KVM VMX's emulation support for !unrestricted_guest punts exceptions to userspace instead of attempting to synthesize the exception with all the correct state (and stack switching, etc...). Punting is acceptable as there's never been a request to support injecting exceptions when emulating due to invalid state, but KVM has historically assumed that userspace will do the right thing and either clear the exception or kill the guest. Deliberately do the opposite and attempt to re-enter the guest with a pending exception and emulation required to verify KVM continues to punt the combination to userspace, e.g. doesn't explode, WARN, etc...

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.
