cpumask_next_wrap_old() has two additional parameters, comparing to its
generic counterpart find_next_bit_wrap(). The reason for that is
historical.
Before 4fe49b3b97c262 ("lib/bitmap: introduce for_each_set_bit_wrap()
macro"), cpumask_next_wrap() was used to implement for_each_cpu_wrap()
iterator. Now that the iterator is an alias to generic
for_each_set_bit_wrap(), the additional parameters aren't used and may
confuse readers.
All existing users call cpumask_next_wrap() in a way that makes it
possible to turn it to straight and simple alias to find_next_bit_wrap().
In a couple of places kernel users opencode missing cpumask_next_and_wrap().
Add it as well.

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 reStructuredText 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.
