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.
