Merge tag 'perf-core-for-mingo-4.21-20181217' 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:

- Introduce 'perf record --aio' to use asynchronous IO trace writing, disabled
  by default (Alexey Budankov)

- Add fallback routines to be used in places where we don't have the CPU mode
  (kernel/userspace/hypervisor) and thus must first fallback lookups looking
  at all map trees when trying to resolve symbols (Adrian Hunter)

- Fix error with config term "pt=0", where we should just force "pt=1" and
  warn the user about the former being nonsensical (Adrian Hunter)

- Fix 'perf test' entry where we expect 'sleep' to come in a PERF_RECORD_COMM
  but instead we get 'coreutils' when sleep is provided by some versions of
  the 'coreutils' package (Adrian Hunter)

- Introduce 'perf top --kallsyms file' to match 'perf report --kallsyms', useful
  when dealing with BPF, where symbol resolution happens via kallsyms, not via
  the default vmlinux ELF symtabs (Arnaldo Carvalho de Melo)

- Support 'srccode' output field in 'perf script' (Andi Kleen)

- Introduce basic 'perf annotation' support for the ARC architecture (Eugeniy Paltsev)

- Compute and display average IPC and IPC coverage per symbol in 'perf annotate' and
  'perf report' (Jin Yao)

- Make 'perf top' use ordered_events and process histograms in a separate thread (Jiri Olsa)

- Make 'perf trace' use ordered_events (Jiri Olsa)

- Add support for ETMv3 and PTMv1.1 decoding in cs-etm (Mathieu Poirier)

- Support for ARM A32/T32 instruction sets in CoreSight trace (cs-etm) (Robert Walker)

- Fix 'perf stat' shadow stats for clock events. (Ravi Bangoria)

- Remove needless rb_tree extra indirection from map__find() (Eric Saint-Etienne)

- Fix CSV mode column output for non-cgroup events in 'perf stat' (Stephane Eranian)

- Add sanity check to libtraceevent's is_timestamp_in_us() (Tzvetomir Stoyanov)

- Use ERR_CAST instead of ERR_PTR(PTR_ERR()) (Wen Yang)

- Fix Load_Miss_Real_Latency on SKL/SKX intel vendor event files (Andi Kleen)

- strncpy() fixes triggered by new warnings on gcc 8.2.0 (Arnaldo Carvalho de Melo)

- Handle tracefs syscall tracepoint older 'nr' field in 'perf trace', that got
  renamed to '__syscall_nr' to work in older kernels (Arnaldo Carvalho de Melo)

- Give better hint about devel package for libssl (Arnaldo Carvalho de Melo)

- Fix the 'perf trace' build in architectures lacking explicit mmap.h file (Arnaldo Carvalho de Melo)

- Remove extra rb_tree traversal indirection from map__find() (Eric Saint-Etienne)

- Disable breakpoint tests for 32-bit ARM (Florian Fainelli)

- Fix typos all over the place, mostly in comments, but also in some debug
  messages and JSON files (Ingo Molnar)

- Allow specifying proc-map-timeout in config file (Mark Drayton)

- Fix mmap_flags table generation script (Sihyeon Jang)

- Fix 'size' parameter to snprintf in the 'perf config' code (Sihyeon Jang)

- More libtraceevent renames to make it a proper library (Tzvetomir Stoyanov)

- Implement new API tep_get_ref() in libtraceevent (Tzvetomir Stoyanov)

- Added support for pkg-config in libtraceevent (Tzvetomir Stoyanov)
