Pull powerpc fixes from Michael Ellerman:
"Some more powerpc fixes for 4.14.
This is bigger than I like to send at rc7, but that's at least partly
because I didn't send any fixes last week. If it wasn't for the IMC
driver, which is new and getting heavy testing, the diffstat would
look a bit better. I've also added ftrace on big endian to my test
suite, so we shouldn't break that again in future.
- A fix to the handling of misaligned paste instructions (P9 only),
where a change to a #define has caused the check for the
instruction to always fail.
- The preempt handling was unbalanced in the radix THP flush (P9
only). Though we don't generally use preempt we want to keep it
working as much as possible.
- Two fixes for IMC (P9 only), one when booting with restricted
number of CPUs and one in the error handling when initialisation
fails due to firmware etc.
- A revert to fix function_graph on big endian machines, and then a
rework of the reverted patch to fix kprobes blacklist handling on
big endian machines.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
