Merge tag 'perf-core-for-mingo-4.16-20171206' 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:
- Improve build messages for files needed by Intel-PT, originally copied
from the kernel sources, that drifted from its original (Adrian Hunter)
- Allow computing 'perf stat' style metrics in 'perf script' (Andi Kleen)
- Fix 'perf report -D' output for user metadata events (Arnaldo Carvalho de Melo)
- Add feature test for pthread_barrier_t availability (Arnaldo Carvalho de Melo)
- Allow again using x86's asm.h when building for the 'bpf' clang target,
making some 'perf test' LLVM/BPF entries work again (Arnaldo Carvalho de Melo)
- Use cpumaps in 'perf bench futex', eliminating some code duplication
(Davidlohr Bueso)
- Improve PMU infrastructure to support amp64's ThunderX2 implementation
defined core events (Ganapatrao Kulkarni)
- Add hint about how to add USDT probes for Node.js (Hansuk Hong)
- s/390 needs -fPIC to be incrementally linked or linked to shared
libraries (Hendrik Brueckner)
- Use pthread_barrier to synch 'perf bench futex wake-parallel' waker
threads (James Yang)
- Fix up build in hardened environments, such as Fedora 27 (Jiri Olsa)
- Add a tip about cacheline events in 'perf c2c' (Sangwon Hong)
- Set browser mode right before setup_browser(), because we may have
errors printed before that, which were getting lost (Seokho Song)
- s390x doesn't support PERF_TYPE_BREAKPOINT, so disable 'perf test'
cases 19 and 20 on s390x, that tests that feature (Thomas Richter)
- Fix unnecessary memory allocation for s390x 'perf annotate' objdump
parsing, which could lead to thousands of needless entries in the
instruction handling array (Thomas Richter)
- Fix objdump comment parsing for Intel mov dissassembly (Thomas Richter)
- Clarify usage of 'overwrite' and 'backward' in the evlist/mmap code,
removing the 'overwrite' parameter from several functions as it was
always used it as 'false' (Wang Nan)
- Fix 'perf record' backward recording, it wasn't doing what was
expected: overwriting records when the ring buffer gets full (Wang Nan)
- Use more flexible pattern matching for CPU identification for perf
vendor event's mapfile.csv, removing the need for a new perf binary
for a sligthly different chip revision that shares the same set of
counters (William Cohen)
