    Linus Torvalds authored
    Pull perf updates from Ingo Molnar:
     "The main kernel changes were:
    
       - add support for Intel's "adaptive PEBS v4" - which embedds LBS data
         in PEBS records and can thus batch up and reduce the IRQ (NMI) rate
         significantly - reducing overhead and making call-graph profiling
         less intrusive.
    
       - add Intel CPU core and uncore support updates for Tremont, Icelake,
    
       - extend the x86 PMU constraints scheduler with 'constraint ranges'
         to better support Icelake hw constraints,
    
       - make x86 call-chain support work better with CONFIG_FRAME_POINTER=y
    
       - misc other changes
    
      Tooling changes:
    
       - updates to the main tools: 'perf record', 'perf trace', 'perf
         stat'
    
       - updated Intel and S/390 vendor events
    
       - libtraceevent updates
    
       - misc other updates and fixes"
