[ Upstream commitdfa03fff86] The size of the CPU affinity mask must be large enough for systems with a very large number of CPUs. Otherwise, tests which try to determine the first online CPU by calling sched_getaffinity() will fail. This makes sure that the size of the allocated affinity mask is dependent on the number of CPUs as reported by get_nprocs_conf().

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.
