commit19331e84c3upstream. Commit6c730bfc89("modpost: handle -ffunction-sections") added ".text.*" to the OTHER_TEXT_SECTIONS macro to fix certain section mismatch warnings. Unfortunately, this makes it impossible for modpost to warn about section mismatches with LTO, which implies '-ffunction-sections', as all functions are put in their own '.text.<func_name>' sections, which may still reference functions in sections they are not supposed to, such as __init. Fix this by moving ".text.*" into TEXT_SECTIONS, so that configurations with '-ffunction-sections' will see warnings about mismatched 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.
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.
