numa_distance in cpu_attach_domain() is introduced in commitb5b217346d("sched/topology: Warn when NUMA diameter > 2") to warn user when NUMA diameter > 2 as we'll misrepresent the scheduler topology structures at that time. This is fixed by Barry in commit585b6d2723("sched/topology: fix the issue groups don't span domain->span for NUMA diameter > 2") and numa_distance is unused now. So remove it.

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.
