Hi Linus,

Please pull 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.

cheers

  powerpc/64s: Fix i-side SLB miss bad address handler saving nonvolatile GPRs (2018-03-26 07:40:17 +1100)

- ----------------------------------------------------------------
powerpc fixes for 4.16 #6

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.

Thanks to:
  Aneesh Kumar K.V, Balbir Singh, Benjamin Herrenschmidt, Nicholas Piggin.
