      Pull fix for ftrace function tracer/profiler conflict from Steven Rostedt:
       "The rewrite of the ftrace code that makes it possible to allow for
        separate trampolines had a design flaw with the interaction between
        the function and function_graph tracers.
        The main flaw was the simplification of the use of multiple tracers
        having the same filter (like function and function_graph, that use the
        set_ftrace_filter file to filter their code).  The design assumed that
        the two tracers could never run simultaneously as only one tracer can
        be used at a time.  The problem with this assumption was that the
        function profiler could be implemented on top of the function graph
        tracer, and the function profiler could run at the same time as the
        function tracer.  This caused the assumption to be broken and when
        ftrace detected this failed assumpiton it would spit out a nasty
        warning and shut itself down.
        Instead of using a single ftrace_ops that switches between the
        function and function_graph callbacks, the two tracers can again use
        their own ftrace_ops.  But instead of having a complex hierarchy of
        ftrace_ops, the filter fields are placed in its own structure and the
        ftrace_ops can carefully use the same filter.  This change took a bit
        to be able to allow for this and currently only the global_ops can
        share the same filter, but this new design can easily be modified to
        allow for any ftrace_ops to share its filter with another ftrace_ops.
        The first four patches deal with the change of allowing the ftrace_ops
        to share the filter (and this needs to go to 3.16 as well).
        The fifth patch fixes a bug that was also caused by the new changes
        but only for archs other than x86, and only if those archs implement a
        direct call to the function_graph tracer which they do not do yet but
        will in the future.  It does not need to go to stable, but needs to be
        fixed before the other archs update their code to allow direct calls
        to the function_graph trampoline"

      ftrace: Use current addr when converting to nop in __ftrace_replace_code() · 39b5552c
      Steven Rostedt (Red Hat) authored
      In __ftrace_replace_code(), when converting the call to a nop in a function
      it needs to compare against the "curr" (current) value of the ftrace ops, and
      not the "new" one. It currently does not affect x86 which is the only arch
      to do the trampolines with function graph tracer, but when other archs that do
      depend on this code implement the function graph trampoline, it can crash.
      Here's an example when ARM uses the trampolines (in the future):

      ftrace: Fix function_profiler and function tracer together · 5f151b24
      Steven Rostedt (Red Hat) authored
      The latest rewrite of ftrace removed the separate ftrace_ops of
      the function tracer and the function graph tracer and had them
      share the same ftrace_ops. This simplified the accounting by removing
      the multiple layers of functions called, where the global_ops func
      would call a special list that would iterate over the other ops that
      were registered within it (like function and function graph), which
      itself was registered to the ftrace ops list of all functions
      currently active. If that sounds confusing, the code that implemented
      it was also confusing and its removal is a good thing.
      The problem with this change was that it assumed that the function
      and function graph tracer can never be used at the same time.
      This is mostly true, but there is an exception. That is when the
      function profiler uses the function graph tracer to profile.
      The function profiler can be activated the same time as the function
      tracer, and this breaks the assumption and the result is that ftrace
      will crash (it detects the error and shuts itself down, it does not
      cause a kernel oops).
      To solve this issue, a previous change allowed the hash tables
      for the functions traced by a ftrace_ops to be a pointer and let
      multiple ftrace_ops share the same hash. This allows the function
      and function_graph tracer to have separate ftrace_ops, but still
      share the hash, which is what is done.
      Now the function and function graph tracers have separate ftrace_ops
      again, and the function tracer can be run while the function_profile
      is active.
