It turns out it was never just gcc-11 that was broken. Apparently it just happens to work on x86-64 with other gcc versions. On arm64, I see warnings with gcc version 13.2.1, and the kernel test robot reports the same problem on s390 with gcc 13.2.0. Admittedly it seems to be just the new Xe drm driver, but this is keeping me from doing my normal arm64 build testing. So it gets reverted until somebody figures out what causes the problem (and why it doesn't show on x86-64, which is what makes me suspect it was never just about gcc-11, and more about just random happenstance). This also changes the Kconfig naming a bit - just make the "disable this for GCC" conditional be one simple Kconfig entry, and we can put the gcc version dependencies in that entry once we figure out what the correct rules are. The version dependency _may_ still end up being "gcc version larger than 11" if the issue is purely in the Xe driver, but even if that ends up the case, let's make that all part of the "GCC_NO_STRINGOP_OVERFLOW" logic. For now, we just disable it for all gcc versions while the exact cause is unknown. Link: https://lore.kernel.org/all/202401161031.hjGJHMiJ-lkp@intel.com/T/ Cc: Gustavo A. R.

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.
