#     powerpc/64: Don't trace code that runs with the soft irq mask unreconciled
#     
#     "Reconciling" in terms of interrupt handling, is to bring the soft irq
#     mask state in to synch with the hardware, after an interrupt causes
#     MSR[EE] to be cleared (while the soft mask may be enabled, and hard
#     irqs not marked disabled).
#     
#     General kernel code should not be called while unreconciled, because
#     local_irq_disable, etc. manipulations can cause surprising irq traces,
#     and it's fragile because the soft irq code does not really expect to
#     be called in this situation.
#     
#     When exiting from an interrupt, MSR[EE] is cleared to prevent races,
#     but soft irq state is enabled for the returned-to context, so this is
#     now an unreconciled state. restore_math is called in this state, and
#     that can be ftraced, and the ftrace subsystem disables local irqs.
#     
#     Mark restore_math and its callees as notrace. Restore a sanity check
#     in the soft irq code that had to be disabled for this case, by commit
#     4da1f79227ad4 ("powerpc/64: Disable irq restore warning for now").
