#     powerpc/pseries: Mark accumulate_stolen_time() as notrace
#     
#     accumulate_stolen_time() is called prior to interrupt state being
#     reconciled, which can trip the warning in arch_local_irq_restore():
#     
#       WARNING: CPU: 5 PID: 1017 at arch/powerpc/kernel/irq.c:258 .arch_local_irq_restore+0x9c/0x130
#       ...
#       NIP .arch_local_irq_restore+0x9c/0x130
#       LR  .rb_start_commit+0x38/0x80
#       Call Trace:
#         .ring_buffer_lock_reserve+0xe4/0x620

#     
#     For now just mark it as notrace. We may change the ordering to call it
#     after interrupt state has been reconciled, but that is a larger
#     change.
