Merge tag 'perf-core-for-mingo-5.0-20190121' 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:

BPF:

  Song Liu:

  - Introduce PERF_RECORD_KSYMBOL to allow tooling to notice the addition
    of new kernel symbols and be able to resolve samples in such symbols.

  - Introduce PERF_RECORD_BPF_EVENT to notify tooling about the loading
    and unloading of BPF programs, making them visible and allowing for
    the request of further information to allow for things like annotation.

  - Change the userspace perf tools to handle those new events and to
    synthesize them for pre-existing loaded BPF programs.

Kernel:

  Arnaldo Carvalho de Melo:

  - Make perf_event_output() propagate the output() return, allowing
    users to check for -ENOSPC in the ring buffer.

perf report:

  Thomas Richter:

  - Display arch specific diagnostic counter sets, starting with s390
    diagnostic counter sets.

perf session:

  Jiri Olsa:

  - Introduce a reader object to prep for multithreaded processing
    of recorded events.

Misc:

  Rasmus Villemoes:

  - Replace automatic const char[] variables by statics, to avoid
    initializing them at runtime, instead having them in .rodata,
    reducing code size.

  YueHaibing:

  - Remove duplicated workqueue.h include from perf_event.h

  Brajeswar Ghosh:

  - Remove some more duplicated headers.
