The function in fact traverses a "bitmap" stored in GPR regs A1 and A2, but does it in a non-obvious way by creating a single-word bitmap twice. This patch switches the function to create a single 2-word bitmap, and also employs for_each_set_bit() macro, as it helps to drop most of the housekeeping code. While there, convert the function to return void to not confuse readers with unchecked result.

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.
