  selftests/powerpc: Fix to use ucontext_t instead of struct ucontext (2018-02-13 22:44:18 +1100)

----------------------------------------------------------------
powerpc fixes for 4.16 #2

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.
