Using the interrupt affinity mask for checking locality is not really working well on architectures which support effective affinity masks. The affinity mask is either the system wide default or set by user space, but the architecture can or even must reduce the mask to the effective set, which means that checking the affinity mask itself does not really tell about the actual target CPUs.

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.
