    Linus Torvalds authored
    Pull perf changes from Ingo Molnar:
     "Lots of changes:
    
       - (much) improved assembly annotation support in perf report, with
         jump visualization, searching, navigation, visual output
         improvements and more.
    
        - kernel support for AMD IBS PMU hardware features.  Notably 'perf
          record -e cycles:p' and 'perf top -e cycles:p' should work without
          skid now, like PEBS does on the Intel side, because it takes
          advantage of IBS transparently.
    
        - the libtracevents library: it is the first step towards unifying
          tracing tooling and perf, and it also gives a tracing library for
          external tools like powertop to rely on.
    
        - infrastructure: various improvements and refactoring of the UI
          modules and related code
    
        - infrastructure: cleanup and simplification of the profiling
          targets code (--uid, --pid, --tid, --cpu, --all-cpus, etc.)
    
        - tons of robustness fixes all around
    
        - various ftrace updates: speedups, cleanups, robustness
          improvements.
    
        - typing 'make' in tools/ will now give you a menu of projects to
          build and a short help text to explain what each does.
    
        - ... and lots of other changes I forgot to list.
    
      The perf record make bzImage + perf report regression you reported
      should be fixed."
