We have support for emulating a number of deprecated instructions in the kernel with individual Kconfig options enabling this support per instruction. In addition to the Kconfig options we also provide runtime control via sysctls but this is not currently mentioned in the Kconfig so not very discoverable for users. This is particularly important for SWP/SWPB since this is disabled by default at runtime and must be enabled via the sysctl, causing considerable frustration for users who have enabled the config option and are then confused to find that the instruction is still faulting. Add a reference to the sysctls in the help text for each of the config options, noting that SWP/SWPB is disabled by default, to improve the user experience.

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.
