Extend sev_smoke_test to also run a minimal SEV-ES smoke test so that it's possible to test KVM's unique VMRUN=>#VMEXIT path for SEV-ES guests without needing a full blown SEV-ES capable VM, which requires a rather absurd amount of properly configured collateral. Punt on proper GHCB and ucall support, and instead use the GHCB MSR protocol to signal test completion. The most important thing at this point is to have _any_ kind of testing of KVM's __svm_sev_es_vcpu_run().

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.
