Merge tag 'perf-urgent-for-mingo-4.20-20181106' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

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

Intel PT SQL viewer: (Adrian Hunter)

- Fall back to /usr/local/lib/libxed.so
- Add Selected branches report
- Add help window
- Fix table find when table re-ordered

Intel PT debug log (Adrian Hunter)

- Add more event information
- Add MTC and CYC timestamps

perf record: (Andi Kleen)

- Support weak groups, just like with 'perf stat'

perf trace: (Arnaldo Carvalho de Melo)

- Start augmenting raw_syscalls:{sys_enter,sys_exit}: goal is to have a
  generic, arch independent eBPF kernel component that is programmed with
  syscall table details, what to copy, how many bytes, pid, arg filters from the
  userspace via eBPF maps by the 'perf trace' tool that continues to use all its
  argument beautifiers, just taking advantage of the extra pointer contents.

JVMTI: (Gustavo Romero)

- Fix undefined symbol scnprintf in libperf-jvmti.so

perf top: (Jin Yao)

- Display the LBR stats in callchain entries

perf stat: (Thomas Richter)

- Handle different PMU names with common prefix

arm64: Will (Deacon)

- Fix arm64 tools build failure wrt smp_load_{acquire,release}.
