When the kernel is configured with CONFIG_NR_CPUS smaller than the number of CPU nodes in the device tree(DT), all the CPU nodes parsing done to fetch topology information will fail. This is not reasonable as it is legal to have all the physical CPUs in the system in the DT. Let us just skip such CPU DT nodes that are not used in the kernel rather than returning an error.

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.
