Add a module parameter cryptomgr.panic_on_fail which causes the kernel
to panic if any crypto self-tests fail.

Use cases:

- More easily detect crypto self-test failures by boot testing,
  e.g. on KernelCI.
- Get a bug report if syzkaller manages to use the template system to
  instantiate an algorithm that fails its self-tests.

The command-line option "fips=1" already does this, but it also makes
other changes not wanted for general testing, such as disabling
"unapproved" algorithms.  panic_on_fail just does what it says.

History
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.
