The stringop and format warnings got disabled globally when they were
newly introduced in commit bd664f6b3e376 ("disable new gcc-7.1.1 warnings
for now"), 217c3e0196758 ("disable stringop truncation warnings for now")
and 5a76021c2eff7 ("gcc-10: disable 'stringop-overflow' warning for now").
In all cases, the sentiment at the time was that the warnings are
useful, and we actually addressed a number of real bugs based on
them, but we never managed to eliminate them all because even the
build bots using W=1 builds only see the -Wstringop-truncation
warnings that are enabled at that level.
Move these into the W=1 section to give them a larger build coverage
and actually eliminate them over time.

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.
