When facility.76 MSAX3 is present for the guest we must issue a validity
interception if the CRYCBD is not valid.
The bit CRYCBD.31 is an effective field and tested at each guest level
and has for effect to mask the facility.76
It follows that if CRYCBD.31 is clear and AP is not in use we do not
have to test the CRYCBD validatity even if facility.76 is present in the
host.

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.
