Right now, the set of features that are stored in the VMSA upon initialization is fixed and depends on the module parameters for kvm-amd.ko. However, the hypervisor cannot really change it at will because the feature word has to match between the hypervisor and whatever computes a measurement of the VMSA for attestation purposes. Add a field to kvm_sev_info that holds the set of features to be stored in the VMSA; and query it instead of referring to the module parameters. Because KVM_SEV_INIT and KVM_SEV_ES_INIT accept no parameters, this does not yet introduce any functional change, but it paves the way for an API that allows customization of the features per-VM.

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 reStructuredText 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.
