Three tests are added:
- invalidate_pkt_pointers_by_tail_call checks that one can use the
packet pointer after a tail call. This was originally possible
and also poses not problems, but was made impossible by 1a4607ffba.
- invalidate_pkt_pointers_by_static_tail_call tests a corner case
found by Eduard Zingerman during the discussion of the original fix,
which was broken in that fix.
- subprog_result_tail_call tests that precision propagation works
correctly across tail calls. This did not work before.

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.
