Nicholas Piggin 31284f703d powerpc/microwatt: add POWER9_CPU, clear PPC_64S_HASH_MMU
Microwatt implements a subset of ISA v3.0 (which is equivalent to
the POWER9_CPU option). It is radix-only, so does not require hash
MMU support.

This saves 20kB compressed dtbImage and 56kB vmlinux size.

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.
