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.
