We currently export the bpf_cpumask_any() and bpf_cpumask_any_and() kfuncs. Intuitively, one would expect these to choose any CPU in the cpumask, but what they actually do is alias to cpumask_first() and cpmkas_first_and(). This is useless given that we already export bpf_cpumask_first() and bpf_cpumask_first_and(), so this patch replaces them with kfuncs that call cpumask_any_distribute() and cpumask_any_and_distribute(), which actually choose any CPU from the cpumask (or the AND of two cpumasks for the latter).

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.
