#     
#     Pull powerpc fix from Michael Ellerman:
#      "Fix a bug introduced by the changes we made to lockless page table
#       walking this cycle.
#     
#       When using the hash MMU, and perf with callchain recording, we can
#       deadlock if the PMI interrupts a hash fault, and the callchain
#       recording then takes a hash fault on the same page.
#     
#       Thanks to Nicholas Piggin, Aneesh Kumar K.V, Anton Blanchard, and
#       Athira Rajeev"
