      Merge tag 'perf-core-for-mingo-5.6-20200106' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
      
      Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
      
      perf record:
      
        Alexey Budankov:
      
        - Adapt affinity for machines with #CPUs > 1K to overcome current 1024 CPUs
          mask size limitation of cpu_set_t type.
      
      perf report/top TUI:
      
        Arnaldo Carvalho de Melo:
      
        - Make ENTER consistently present the pop up menu with and without call
          chains, to eliminate confusion. The menu continues available at all times
          use 'm' and '+' can be used to toggle just one call chain level, 'e' for all
          the call chains for a top level histogram entry and 'E' to expand all call
          chains in all top level entries. Extra info about these options was added to
          the pop up menu entries. Pressing 'k' serves as special hotkey to go straight
          to the main vmlinux entries, to avoid having to press enter and then select
          "Zoom into the kernel DSO".
      
      perf sched timehist:
      
        David Ahern:
      
        - Add support for filtering on CPU.
      
      perf tests:
      
        Arnaldo Carvalho de Melo:
      
        - Show expected versus obtained values in bp_signal test.
      
      libperf:
      
        Jiri Olsa:
      
        - Move to tools/lib/perf.
      
        - Add man pages.
      
      libapi:
      
        Andrey Zhizhikin:
      
        - Fix gcc9 stringop-truncation compilation error.
      
      tools lib:
      
        Vitaly Chikunov:
      
        - Fix builds when glibc contains strlcpy(), which is the case for ALT Linux.

      pipe: fix empty pipe check in pipe_write() · 0dd1e377
      Jan Stancek authored
      LTP pipeio_1 test is hanging with v5.5-rc2-385-gb8e382a1,
      with read side observing empty pipe and sleeping and write
      side running out of space and then sleeping as well. In this
      scenario there are 5 writers and 1 reader.
      
      Problem is that after pipe_write() reacquires pipe lock, it
      re-checks for empty pipe with potentially stale 'head' and
      doesn't wake up read side anymore. pipe->tail can advance
      beyond 'head', because there are multiple writers.
      
      Use pipe->head for empty pipe check after reacquiring lock
      to observe current state.
      
      Testing: With patch, LTP pipeio_1 ran successfully in loop for 1 hour.
               Without patch it hanged within a minute.
