Implement support for hash guests under hash host. This has to save and restore the host SLB, and ensure that the MMU is off while switching into the guest SLB. POWER9 and later CPUs now always go via the P9 path. The "fast" guest mode is now renamed to the P9 mode, which is consistent with its functionality and the rest of the naming.

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.
