Linux kernel source tree

When running tests, we should probably accept any help we can get when it comes to detecting issues early or making them more debuggable. We have seen a few cases where a test_progs_noalu32 run, for example, encountered a soft lockup and stopped making progress. It was only interrupted once we hit the overall test timeout [0]. We can not and do not want to necessarily rely on test timeouts, because those rely on infrastructure provided by the environment we run in (and which is not present in tools/testing/selftests/bpf/vmtest.sh, for example). To that end, let's enable panics on soft as well as hard lockups to fail fast should we encounter one. That's happening in the configuration indented to be used for selftests (including when using vmtest.sh or when running in BPF CI).

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.
