On most arches having function flush_dcache_range(), including PPC32, this function does a writeback and invalidation of the cache bloc. On PPC64, flush_dcache_range() only does a writeback while flush_inval_dcache_range() does the invalidation in addition. In addition it looks like within arch/powerpc/, there are no PPC64 platforms using flush_dcache_range() This patch drops the existing 64 bits version of flush_dcache_range() and renames flush_inval_dcache_range() into flush_dcache_range().

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.
