YueHaibing 04ff4863e1 libnvdimm/region: Fix build error 
On CONFIG_PPC32=y build fails:

drivers/nvdimm/region_devs.c:1034:14: note: in expansion of macro ‘do_div’
  remainder = do_div(per_mapping, mappings);
              ^~~~~~

   __rem = __div64_32(&(n), __base); \

Use div_u64 instead of do_div to fix this.

README 

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.
