Linux kernel source tree

Even though unwinding depends on either HAVE_DWARF_SUPPORT or HAVE_LIBUNWIND, scripts testing unwinding can't just look for the existence of either of those flags. This is because NO_LIBDW_DWARF_UNWIND=1 can disable unwinding with libdw, but libdw will still be linked leaving HAVE_DWARF_SUPPORT turned on. Presumably because it is used for things other than unwinding, so I don't think this needs to be fixed. HAVE_DWARF_UNWIND_SUPPORT already takes the combination of all those things into account, and is used to gate the built in tests like "Test dwarf unwind", so add it to the feature list output so that it can be used by the script tests too.

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.
