      Merge branch 'perf/annotate' of... · 149936a0

      Merge branch 'perf/annotate' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
      
      Perf annotate browser improvements:
      
       - Get back the line separating the overheads from the disassembly, requested by
         Peter Zijlstra, Linus agreed now that it is a solid line and more column real
         state was harvested. Also it has the jump->arrow lines separated from it by
         the address/jump target column.
      
       - Don't change asm line color when toggling source code view. Requested by
         Peter Zijlstra.

      Additionally we were not checking if a cpu list had been provided by the
      user. Fix that.

      tracing: Prevent wasting time evaluating parameters in trace_preempt_on/off · b02ee9a3
      Minho Ban authored
      This fixes spending time for evaluating parameters in trace_preempt_on/off when
      the tracer config is off.
      
      The patch mainly inspired by Steven Rostedt, thanks Steven.
