Bail early from svm_enable_nmi_window() for SEV-ES guests without trying to enable single-step of the guest, as single-stepping an SEV-ES guest is impossible and the guest is responsible for *telling* KVM when it is ready for an new NMI to be injected. Functionally, setting TF and RF in svm->vmcb->save.rflags is benign as the field is ignored by hardware, but it's all kinds of confusing.

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.
