mainlining shenanigans

Enabling CONFIG_GCOV_PROFILE_ALL=y causes linker errors on ARM: `.text.exit' referenced in section `.ARM.exidx.text.exit': defined in discarded section `.text.exit' `.text.exit' referenced in section `.fini_array.00100': defined in discarded section `.text.exit' And related errors on NDS32: `.text.exit' referenced in section `.dtors.65435': defined in discarded section `.text.exit' The gcov compiler flags cause certain compiler versions to generate additional destructor-related sections that are not yet handled by the linker script, resulting in references between discarded and non-discarded sections. Since destructors are not used in the Linux kernel, fix this by discarding these additional sections.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
