David Laight 500db21917 lib: add tests for mul_u64_u64_div_u64_roundup()
Replicate the existing mul_u64_u64_div_u64() test cases with round up. 
Update the shell script that verifies the table, remove the comment
markers so that it can be directly pasted into a shell.

Rename the divisor from 'c' to 'd' to match mul_u64_add_u64_div_u64().

It any tests fail then fail the module load with -EINVAL.

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.
