When querying whether or not eVMCS is enabled on behalf of the guest, treat eVMCS as enable if and only if Hyper-V is enabled/exposed to the guest. Note, flows that come from the host, e.g. KVM_SET_NESTED_STATE, must NOT check for Hyper-V being enabled as KVM doesn't require guest CPUID to be set before most ioctls().

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.
