Pull powerpc fixes from Michael Ellerman:
"A larger batch of fixes than we'd like. Roughly 1/3 fixes for new
code, 1/3 fixes for stable and 1/3 minor things.
There's four commits fixing bugs when using 16GB huge pages on hash,
caused by some of the preparatory changes for pkeys.
Two fixes for bugs in the enhanced IRQ soft masking for local_t, one
of which broke KVM in some circumstances.
Four fixes for Power9. The most bizarre being a bug where futexes
stopped working because a NULL pointer dereference didn't trap during
early boot (it aliased the kernel mapping). A fix for memory hotplug
when using the Radix MMU, and a fix for live migration of guests using
the Radix MMU.
Two fixes for hotplug on pseries machines. One where we weren't
correctly updating NUMA info when CPUs are added and removed. And the
other fixes crashes/hangs seen when doing memory hot remove during
boot, which is apparently a thing people do.
Finally a handful of build fixes for obscure configs and other minor
fixes.
