Mainline Linux tree for various devices, only for fun :)

Currently it's not possible to enable DEBUG_INFO for an all*config build, since it is marked as "depends on !COMPILE_TEST". This generally makes sense because a debug build of an all*config target ends up taking much longer and the output is much larger. Having this be "default off" makes sense. However, there are cases where enabling DEBUG_INFO for such builds is useful for doing treewide A/B comparisons of build options, etc. Make DEBUG_INFO selectable from any of the DWARF version choice options, with DEBUG_INFO_NONE being the default for COMPILE_TEST. The mutually exclusive relationship between DWARF5 and BTF must be inverted, but the result remains the same. Additionally moves DEBUG_KERNEL and DEBUG_MISC up to the top of the menu because they were enabling features _above_ it, making it weird to navigate menuconfig.

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.
