When checking an address is located in a global data section also check for the .bss section as global variables initialized to 0 can be in there (-fzero-initialized-in-bss). This was found when looking at ensure_safe_net_sysctl which was failing to detect non-init sysctl pointing to a global data section when the data was in the .bss section.

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.
