If the KSS facility is available on the machine, we also make it available for our KVM guests. The KSS facility bypasses storage key management as long as the guest does not issue a related instruction. When that happens, the control is returned to the host, which has to turn off KSS for a guest vcpu before retrying the instruction. Signed-off-by: Corey S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
