A mirror of the official Linux kernel repository just in case
6a022dd29f
The 64-bit overflow tests will trigger 64-bit division on 32-bit hosts,
which is not currently used anywhere in the kernel, and tickles bugs
in at least Clang 13 and earlier:
https://github.com/ClangBuiltLinux/linux/issues/1636
In reality, there shouldn't be a reason to not build the 64-bit test
cases on 32-bit systems, so these #ifdefs can be removed once the minimum
Clang version reaches 13.
In the meantime, silence W=1 warnings given by the current code:

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.
