Introduce a kernel function which is the analogue of dump_stack() printing some useful information and the stack trace. This is not exposed to BPF programs yet, but can be made available in the future. When we have a program counter for a BPF program in the stack trace, also additionally output the filename and line number to make the trace helpful. The rest of the trace can be passed into ./decode_stacktrace.sh to obtain the line numbers for kernel symbols.

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.
