These are actually all fixes for pre-4.16 code, or new hardware workarounds.
Fix missing AT_BASE_PLATFORM (in auxv) when we're using a new firmware interface
for describing CPU features.
Fix lost pending interrupts due to a race in our interrupt soft-masking code.
A workaround for a nest MMU bug with TLB invalidations on Power9.
A workaround for broadcast TLB invalidations on Power9.
Fix a bug in our instruction SLB miss handler, when handling bad addresses
(eg. >= TASK_SIZE), which could corrupt non-volatile user GPRs.

Pull powerpc fixes from Michael Ellerman:
"Some more powerpc fixes for 4.16. Apologies if this is a bit big at
rc7, but they're all reasonably important fixes. None are actually for
new code, so they aren't indicative of 4.16 being in bad shape from
our point of view.
- Fix missing AT_BASE_PLATFORM (in auxv) when we're using a new
firmware interface for describing CPU features.
- Fix lost pending interrupts due to a race in our interrupt
soft-masking code.
- A workaround for a nest MMU bug with TLB invalidations on Power9.
- A workaround for broadcast TLB invalidations on Power9.
- Fix a bug in our instruction SLB miss handler, when handling bad
addresses (eg. >= TASK_SIZE), which could corrupt non-volatile user
GPRs.
