      Pull tracing fixes from Steven Rostedt:
       "This includes two fixes.
      
        1) is a bug fix that happens when root does the following:
      
           echo function_graph > current_tracer
           modprobe foo
           echo nop > current_tracer
      
         This causes the ftrace internal accounting to get screwed up and
         crashes ftrace, preventing the user from using the function tracer
         after that.
      
        2) if a TRACE_EVENT has a string field, and NULL is given for it.
      
         The internal trace event code does a strlen() and strcpy() on the
         source of field.  If it is NULL it causes the system to oops.
      
         This bug has been there since 2.6.31, but no TRACE_EVENT ever passed
         in a NULL to the string field, until now"

      ftrace: Fix function graph with loading of modules · 8a56d776

       "ftrace: Check module functions being traced on reload"
      fixed module loading and unloading with respect to function tracing, but
      it missed the function graph tracer. If you perform the following
      
       # cd /sys/kernel/debug/tracing
       # echo function_graph > current_tracer
       # modprobe nfsd
       # echo nop > current_tracer

      The above mentioned commit didn't go far enough. Well, it covered the
      function tracer by adding checks in __register_ftrace_function(). The
      problem is that the function graph tracer circumvents that (for a slight
      efficiency gain when function graph trace is running with a function
      tracer. The gain was not worth this).
      
      The problem came with ftrace_startup() which should always be called after
      __register_ftrace_function(), if you want this bug to be completely fixed.
      
      Anyway, this solution moves __register_ftrace_function() inside of
      ftrace_startup() and removes the need to call them both.

      New tracepoints have been added that have allowed for NULL pointers
      being assigned to strings. To fix this, change the TRACE_EVENT() code
      to check for NULL and if it is, it will assign "(null)" to it instead
      (similar to what glibc printf does).

      what was before suspending as it's anyway likely that we still don't

      ARM: vexpress/TC2: Implement MCPM power_down_finish() · 33cb667a
      Dave Martin authored
      This patch implements the power_down_finish() method for TC2, to
      enable the kernel to confirm when CPUs are safely powered down.
      
      The information required for determining when a CPU is parked
      cannot be obtained from any single place, so a few sources of
      information must be combined:
      
        * mcpm_cpu_power_down() must be pending for the CPU, so that we
          don't get confused by false STANDBYWFI positives arising from
          CPUidle.  This is detected by waiting for the tc2_pm use count
          for the target CPU to reach 0.
      
        * Either the SPC must report that the CPU has asserted
          STANDBYWFI, or the TC2 tile's reset control logic must be
          holding the CPU in reset.
      
          Just checking for STANDBYWFI is not sufficient, because this
          signal is not latched when the the cluster is clamped off and
          powered down: the relevant status bits just drop to zero.  This
          means that STANDBYWFI status cannot be used for reliable
          detection of the last CPU in a cluster reaching WFI.
      
      This patch is required in order for kexec to work with MCPM on TC2.
      
      MCPM code was changed in commit 0de0d646
      
       ('ARM: 7848/1: mcpm:
      Implement cpu_kill() to synchronise on powerdown'), and since then it
      will hit a WARN_ON_ONCE() due to power_down_finish not being implemented
      on the TC2 platform.

      ARM: tegra: Provide dummy powergate implementation · 9886e1fd
      Thierry Reding authored
      
      
      In order to support increased build test coverage for drivers, implement
      dummies for the powergate implementation. This will allow the drivers to
      be built without requiring support for Tegra to be selected.
      
      This patch solves the following build errors, which can be triggered in
      v3.13-rc1 by selecting DRM_TEGRA without ARCH_TEGRA:
      
      drivers/built-in.o: In function `gr3d_remove':
      drivers/gpu/drm/tegra/gr3d.c:321: undefined reference to `tegra_powergate_power_off'
      drivers/gpu/drm/tegra/gr3d.c:325: undefined reference to `tegra_powergate_power_off'
      drivers/built-in.o: In function `gr3d_probe':
      drivers/gpu/drm/tegra/gr3d.c:266: undefined reference to `tegra_powergate_sequence_power_up'

      From Tony Lindgren:
      Few more fixes for issues found booting older omaps using device tree.
      Also few randconfig build fixes and removal of some dead code for omap4
      as it no longer has legacy platform data based booting support.

      ARM: omap: fix warning with LPAE build · 6dd1e357
      Olof Johansson authored
      
      
      Some omap3 code is throwing a warning:
      arch/arm/mach-omap2/pm34xx.c: In function 'omap3_save_secure_ram_context':
      arch/arm/mach-omap2/pm34xx.c:123:32: warning: cast to pointer from
        integer of different size [-Wint-to-pointer-cast]
      
      In reality this code will never actually execute with LPAE=y, since
      Cortex-A8 doesn't support it. So downcasting the __pa() is safe in
      this case.

      ima: do not send field length to userspace for digest of ima template · 3e8e5503
      Roberto Sassu authored
      This patch defines a new value for the 'ima_show_type' enumerator
      (IMA_SHOW_BINARY_NO_FIELD_LEN) to prevent that the field length
      is transmitted through the 'binary_runtime_measurements' interface
      for the digest field of the 'ima' template.
