Merge tag 'perf-core-for-mingo' 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:

User visible changes:

  - Allow selecting the type of callchains per event, including disabling
    callchains in all but one entry in an event list, to save space, and also
    to ask for the callchains collected in one event to be used in other
    events. (Kan Liang)

  - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho de Melo)
    - A bunch more translate file/pathnames from pointers to strings.
    - Convert numbers to strings for the 'keyctl' syscall 'option' arg.
    - Add missing 'clockid' entries.

  - Fix 'perf probe -L sys_*' as it was not showing all the source code for
    syscall functions in the kernel. (Masami Hiramatsu)

  - Make ESC unzoom as well in the hists browser, i.e. in 'report' and 'top',
    as we're considering repurposing the right and left arrow keys to use in
    horizontal scrolling, i.e. leave just ESC to be used for what <- works
    now, and ENTER for what -> does (they are already aliases for ages).
    (Arnaldo Carvalho de Melo)

Infrastructure fixes:

  - Check for SRCLINE_UNKNOWN case in "srcfile" processing (Andi Kleen)

  - Wrap the slsmg_{printf,write_nstring} slang functions behind ui_browser, so
    that we can make the ui_browser based browsers (annotate, menus, hists, etc) UI
    library agnostic and usable with multiple backends (slang now, GTK+ and others
    in the future, maybe) (Arnaldo Carvalho de Melo)
