Allow the rcu_nocbs kernel parameter to be specified just by itself, without specifying any CPUs. This allows systems administrators to use "rcu_nocbs" to specify that none of the CPUs are to be offloaded at boot time, but than any of them may be offloaded at runtime via cpusets. In contrast, if the "rcu_nocbs" or "nohz_full" kernel parameters are not specified at all, then not only are none of the CPUs offloaded at boot, none of them can be offloaded at runtime, either. While in the area, modernize the description of the "rcuo" kthreads' naming scheme.

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.
