We have two new SIE exit codes dealing with instructions. 104 (0x68) for a secure instruction interception, on which the SIE needs hypervisor action to complete the instruction. We can piggy-back on the existing instruction handlers. 108 which is merely a notification and provides data for tracking and management. For example this is used to tell the host about a new value for the prefix register. As there will be several special case handlers in later patches, we handle this in a separate function.

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.
