First of all, in order to build with clang at all, one must first apply
Valentin Obst's build fix for LLVM [1]. Once that is done, then when
building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang is pickier than gcc, about which version of abs(3) to call,
depending on the argument type:
int abs(int j);
long labs(long j);
long long llabs(long long j);
...and this is causing both build failures and warnings, when running:
make LLVM=1 -C tools/testing/selftests
Fix this by calling labs() in value_close(), because the arguments are
unambiguously "long" type.

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 reStructuredText 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.
