Declare a dedicated struct map_cpu_mask type for cpu masks of arbitrary length. The mask is available thru bits pointer and the mask length is kept in nbits field. MMAP_CPU_MASK_BYTES() macro returns mask storage size in bytes. The mmap_cpu_mask__scnprintf() function can be used to log text representation of the mask. Committer notes: To print the 'nbits' struct member we must use %zd, since it is a size_t, this fixes the build in some toolchains/arches.

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.
