      perf hists: Check if a hist_entry has callchains before using them · fabd37b8
      Arnaldo Carvalho de Melo authored
      So far if we use 'perf record -g' this will make
      symbol_conf.use_callchain 'true' and logic will assume that all events
      have callchains enabled, but ever since we added the possibility of
      setting up callchains for some events (e.g.: -e
      cycles/call-graph=dwarf/) while not for others, we limit usage scenarios
      by looking at that symbol_conf.use_callchain global boolean, we better
      look at each event attributes.
      
      On the road to that we need to look if a hist_entry has callchains, that
      is, to go from hist_entry->hists to the evsel that contains it, to then
      look at evsel->sample_type for PERF_SAMPLE_CALLCHAIN.
      
      The next step is to add a symbol_conf.ignore_callchains global, to use
      in the places where what we really want to know is if callchains should
      be ignored, even if present.
      
      Then -g will mean just to select a callchain mode to be applied to all
      events not explicitely setting some other callchain mode, i.e. a default
      callchain mode, and --no-call-graph will set
      symbol_conf.ignore_callchains with that clear intention.
      
      That too will at some point become a per evsel thing, that tools can set
      for all or just a few of its evsels.

      perf hists: Introduce hist_entry__has_callchain() method · 0b5d6ece
      Arnaldo Carvalho de Melo authored
      We'll use this helper more frequently when reworking
      symbol_conf.use_callchain logic, where knowing if a hist_entry has
      callchains is the important bit, so make going from hist_entry to hists
      to evsel easier, compact.

      - Update prctl and cpufeatures.h tools/ copies with the kernel sources
        originals, which makes 'perf trace' know about the new prctl options
        for speculation control and silences the build warnings (Arnaldo Carvalho de Melo)
      
      - Update insn.h in Intel-PT instruction decoder with its original from from the

       - two patches addressing the problem that the scheduler allows under

         not yet fully booted which causes a few subtle and hard to debug
         issue
      
       - add a missing runqueue clock update in the deadline scheduler which
         triggers a warning under certain circumstances

      Pull SCSI fix from James Bottomley:
       "Eve of merge window fix: The original code was so bogus as to be
        casting the wrong generic device to an rport and proceeding to take
        actions based on the bogus values it found.
      
        Fortunately it seems the location that is dereferenced always exists,
        so the code hasn't oopsed yet, but it certainly annoys the memory
        checkers"
