      Steven Rostedt (Red Hat) 提交于
      As trace event triggers are now part of the mainline kernel, I added
      my trace event trigger tests to my test suite I run on all my kernels.
      Now these tests get run under different config options, and one of
      those options is CONFIG_PROVE_RCU, which checks under lockdep that
      the rcu locking primitives are being used correctly. This triggered
      the following splat:

      Pull ACPI and power management fixes from Rafael Wysocki:
       "A bunch of regression fixes this time.  They fix two regressions in
        the PNP subsystem, one in the ACPI processor driver and one in the
        ACPI EC driver, four cpufreq driver regressions and an unrelated bug
        in one of the drivers.  The regressions are recent or introduced in
        3.14.
      
        Specifics:
      
         - There are two bugs in the ACPI PNP core that cause errors to be
           returned if optional ACPI methods are not present.  After an ACPI
           core change made in 3.14 one of those errors leads to serial port
           suspend failures on some systems.  Fix from Rafael J Wysocki.
      
         - A recently added PNP quirk related to Intel chipsets intorduced a
           build error in unusual configurations (PNP without PCI).  Fix from
           Bjorn Helgaas.
      
         - An ACPI EC workaround related to system suspend on Samsung machines
           added in 3.14 introduced a race causing some valid EC events to be
           discarded.  Fix from Kieran Clancy.
      
         - The acpi-cpufreq driver fails to load on some systems after a 3.14
           commit related to APIC ID parsing that overlooked one corner case.
           Fix from Lan Tianyu.
      
         - Fix for a recently introduced build problem in the ppc-corenet
           cpufreq driver from Tim Gardner.
      
         - A recent cpufreq core change to ensure serialization of frequency
           transitions for drivers with a ->target_index() callback overlooked
           the fact that some of those drivers had been doing operations
           introduced by it into the core already by themselves.  That
           resulted in a mess in which the core and the drivers try to do the
           same thing and block each other which leads to deadlocks.  Fixes
           for the powernow-k7, powernow-k6, and longhaul cpufreq drivers from
           Srivatsa S Bhat.
