      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"

      We are missing building windfarm_max6690_sensor.o when building
      CONFIG_WINDFARM_RM31. Usually all the windfarm drivers are built
      and thus this isn't a problem but some more "tailored" setups
      (Gentoo ?) building only that driver are not working because
      the require sensor module is missing.

      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).

      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: 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.

                if name length is less than 12, the ' ' will be filled before name.

      powerpc/signals: Improved mark VSX not saved with small contexts fix · ec67ad82
      Michael Neuling authored
      In a recent patch:
        commit c13f20ac
        Author: Michael Neuling <mikey@neuling.org>
        powerpc/signals: Mark VSX not saved with small contexts
      We fixed an issue but an improved solution was later discussed after the patch
      was merged.
      Firstly, this patch doesn't handle the 64bit signals case, which could also hit
      this issue (but has never been reported).
      Secondly, the original patch isn't clear what MSR VSX should be set to.  The
      new approach below always clears the MSR VSX bit (to indicate no VSX is in the
      context) and sets it only in the specific case where VSX is available (ie. when
      VSX has been used and the signal context passed has space to provide the
      This reverts the original patch and replaces it with the improved solution.  It
      also adds a 64 bit version.

      powerpc/kdump: Adding symbols in vmcoreinfo to facilitate dump filtering · 8ff81271
      Hari Bathini authored
      When CONFIG_SPARSEMEM_VMEMMAP option is used in kernel, makedumpfile fails
      to filter vmcore dump as it fails to do vmemmap translations. So far
      dump filtering on ppc64 never had to deal with vmemmap addresses seperately
      as vmemmap regions where mapped in zone normal. But with the inclusion of
      CONFIG_SPARSEMEM_VMEMMAP config option in kernel, this vmemmap address
      translation support becomes necessary for dump filtering. For vmemmap adress
      translation, few kernel symbols are needed by dump filtering tool. This patch
      adds those symbols to vmcoreinfo, which a dump filtering tool can use for
      filtering the kernel dump. Tested this changes successfully with makedumpfile
      tool that supports vmemmap to physical address translation outside zone normal.

      CONFIG_CPU_LITTLE_ENDIAN=y gets set but his toolchain is not

      powerpc: Fix error when cross building TAGS & cscope · 924dd50b
      Michael Neuling authored
      Currently if I cross build TAGS or cscope from x86 I get this:
        % make ARCH=powerpc TAGS
        gcc-4.8.real: error: unrecognized command line option ‘-mbig-endian’
        GEN     TAGS
      I'm not setting CROSS_COMPILE= as logically I shouldn't need to and I
      haven't needed to in the past when building TAGS or cscope.  Also, the
      above completess correct as the error is not fatal to the build.
      This was caused by:
          commit d72b0801
          Author: Ian Munsie <imunsie@au1.ibm.com>
          powerpc: Add ability to build little endian kernels
      The below fixes this by testing for the -mbig-endian option before
      adding it.
      I've not done the same thing in the little endian case as if
      -mlittle-endian doesn't exist, we probably want to fail quickly as you
      probably have an old big endian compiler.
