Extend the existing regression test framework for s390x CPU subfunctions to include tests for the PRNO (Perform Random Number Operation), KDSA (Compute Digital Signature Authentication) and KMA (Cipher Message with Authentication) crypto functions. The test procedure follows the established pattern: 1. Obtain KVM_S390_VM_CPU_MACHINE_SUBFUNC attribute for the VM. 2. Execute PRNO, KDSA and KMA instructions. 3. Compare KVM-reported results with direct instruction execution results.

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 reStructuredText 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.
