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