Up to now we always expected to have the storage key facility available for our (non-VSIE) KVM guests. For huge page support, we need to be able to disable it, so let's introduce that now. We add the use_skf variable to manage KVM storage key facility usage. Also we rename use_skey in the mm context struct to uses_skeys to make it more clear that it is an indication that the vm actively uses storage keys.

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.
