Pull powerpc fixes from Michael Ellerman:
"An assortment of non-regression fixes that have accumulated since the
start of the merge window.
- A fix for a user triggerable oops on machines where transactional
memory is disabled, eg. Power9 bare metal, Power8 with TM disabled
on the command line, or all Power7 or earlier machines.
- Three fixes for handling of PMU and power saving registers when
running nested KVM on Power9.
- Two fixes for bugs found while stress testing the XIVE interrupt
controller code, also on Power9.
- A fix to allow guests to boot under Qemu/KVM on Power9 using the
the Hash MMU with >= 1TB of memory.
- Two fixes for bugs in the recent DMA cleanup, one of which could
lead to checkstops.
- And finally three fixes for the PAPR SCM nvdimm driver.

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.
