Sometimes it is useful to see which user opcode bytes RIP points to when a fault happens: be it to rule out RIP corruption, to dump info early during boot, when doing core dumps is impossible due to not having a writable filesystem yet. Sometimes it is useful if debugging an issue and one doesn't have access to the executable which caused the fault in order to disassemble it. That last aspect might have some security implications so show_unhandled_signals could be revisited for that or a new config option added.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
