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:

  - No need to explicitely enable evsels for workload started from perf, let it
    be enabled via perf_event_attr.enable_on_exec, removing some events that take
    place in the 'perf trace' before a workload is really started by it.
    (Arnaldo Carvalho de Melo)

  - Fix to handle optimized not-inlined functions in 'perf probe' (Masami Hiramatsu)

  - Update 'perf probe' man page (Masami Hiramatsu)

  - 'perf trace': Allow mixing with tracepoints and suppressing plain syscalls
    (Arnaldo Carvalho de Melo)

Infrastructure changes:

  - Introduce {trace_seq_do,event_format_}_fprintf functions to allow
    a default tracepoint field list printer to be used in tools that allows
    redirecting output to a file. (Arnaldo Carvalho de Melo)

  - The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE
    must be defined before pthread.h, do it to fix the build in some
    systems (Josh Boyer)

  - Cleanups in 'perf buildid-cache' (Masami Hiramatsu)

  - Fix dso cache test case (Namhyung Kim)

  - Do Not rely on dso__data_read_offset() to open DSO (Namhyung Kim)

  - Make perf aware of tracefs (Steven Rostedt).

  - Fix build by defining STT_GNU_IFUNC for glibc 2.9 and older (Vinson Lee)

  - AArch64 symbol resolution fixes (Victor Kamensky)

  - Kconfig beachhead (Jiri Olsa)

  - Simplify nr_pages validity (Kaixu Xia)

  - Fixup header positioning in 'perf list' (Yunlong Song)
