Pull more tracing fixes from Steven Rostedt:
 "Two more fixes:

   - Change idx variable in DO_TRACE macro to __idx to avoid name
     conflicts. A kvm event had "idx" as a parameter and it confused the
     macro.

   - Fix a race where interrupts would be traced when set_graph_function
     was set. The previous patch set increased a race window that
     tricked the function graph tracer to think it should trace
     interrupts when it really should not have.

     The bug has been there before, but was seldom hit. Only the last
     patch series made it more common"
