#     
#     Pull tracing fixes from Steven Rostedt:
#      "This fixes two annoying bugs:
#     
#        - The first one is a side effect caused by using SRCU for rcuidle
#          tracepoints. It seems that the perf was depending on the rcuidle
#          tracepoints to make RCU watch when it wasn't.
#     
#          The real fix will be to have perf use SRCU instead of depending on
#          RCU watching, but that can't be done until SRCU is safe to use in
#          NMI context (Paul's working on that).
#     
#        - The second bug fix is for a bug that's been periodically making my
#          tests fail randomly for some time. I haven't had time to track it
#          down, but finally have. It has to do with stressing NMIs (via perf)
#          while enabling or disabling ftrace function handling with lockdep
#          enabled.
#     
#          If an interrupt happens and just as it returns, it sets lockdep
#          back to "interrupts enabled" but before it returns an NMI is
#          triggered, and if this happens while printk_nmi_enter has a
#          breakpoint attached to it (because ftrace is converting it to or
#          from nop to call fentry), the breakpoint trap also calls into
#          lockdep, and since returning from the NMI to a interrupt handler,
#          interrupts were disabled when the NMI went off, lockdep keeps its
#          state as interrupts disabled when it returns back from the
#          interrupt handler where interrupts are enabled.
#     
#          This causes lockdep_assert_irqs_enabled() to trigger a false
#          positive"
