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.

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.
