#      "Fix a bug on pseries where spurious wakeups from H_PROD would prevent
#       partition migration from succeeding.
#     
#       Fix oopses seen in pcpu_alloc(), caused by parallel faults of the
#       percpu mapping causing us to corrupt the protection key used for the
#       mapping, and cause a fatal key fault.
#     
#       Thanks to Aneesh Kumar K.V, Murilo Opsfelder Araujo, and Nathan Lynch"
