Commitceef7d10df("KVM: x86: VMX: hyper-v: Enlightened MSR-Bitmap support") broke the build with Hyper-V disabled, because it accesses ms_hyperv.nested_features without checking if that exists. This is the quick-and-hacky build fix. I suspect the proper fix is to replace the static_branch_unlikely(&enable_evmcs) tests with an inline helper function that also checks that CONFIG_HYPERV is enabled, since without that, enable_evmcs makes no sense. But I want a working build environment first and foremost, and I'm upset this slipped through in the first place. My primary build tests missed it because I tend to build with everything enabled, but it should have been caught in the kvm tree.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
