Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible changes:

  - Take tracefs into account when reporting errors about accessing
    tracepoint information in tools like 'perf trace' (Arnaldo Carvalho de Melo)

  - Let user have timestamps with per-thread recording in 'perf record' (Adrian Hunter)

Infrastructure changes:

  - Introduce series of functions to build event filters so that we
    can set them in just one ioctl call, useful to set up common_pid,
    raw_syscalls:sys_{enter,exit}'s "id" filters to use with
    'perf trace' (Arnaldo Carvalho de Melo)

  - Delete an unnecessary check before calling strfilter__delete() (Markus Elfring)
