Add a library/APIs for creating and interfacing with SEV guests, all of which need some amount of common functionality, e.g. an open file handle for the SEV driver (/dev/sev), ioctl() wrappers to pass said file handle to KVM, tracking of the C-bit, etc. Add an x86-specific hook to initialize address properties, a.k.a. the location of the C-bit. An arch specific hook is rather gross, but x86 already has a dedicated #ifdef-protected kvm_get_cpu_address_width() hook, i.e. the ugliest code already exists.

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.
