This enhances the current selftest framework for validating the in-kernel instruction emulation infrastructure by adding support for compute type instructions i.e. integer ALU-based instructions. Originally, this framework was limited to only testing load and store instructions. While most of the GPRs can be validated, support for SPRs is limited to LR, CR and XER for now. When writing the test cases, one must ensure that the Stack Pointer (GPR1) or the Thread Pointer (GPR13) are not touched by any means as these are vital non-volatile registers.

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.
