Subtests are added to exercise the patched code which handles - LLONG_MIN/-1 - INT_MIN/-1 - LLONG_MIN%-1 - INT_MIN%-1 where -1 could be an immediate or in a register. Without the previous patch, all these cases will crash the kernel on x86_64 platform. Additional tests are added to use small values (e.g. -5/-1, 5%-1, etc.) in order to exercise the additional logic with patched insns.

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.
