perf/core improvements and fixes:
- Add support for pmu events vendor subdirectories, move vendor event
files (JSON format) to "arm" and "cavium" subdirectories (John Garry)
- Enable ThunderX2 B0 events in the "cavium" vendor event files (Ganapatrao Kulkarni)
- Show zero counters as well in 'perf report --stat' (Ingo Molnar)
- Record physical addresses in samples in 'perf c2c record', so that
the NUMA node can be displayed for cacheline addresses (Jiri Olsa)
- Fix kernel MMAP name setup when --vmlinux is used (Jiri Olsa)
- Display llvm eBPF compiling command in debug output (Jiri Olsa)
- Add libdw DWARF post unwind support for ARM64 (Jean Pihet, Kim Phillips)
- Unwind with libdw doesn't take symfs into account (Martin Vuille)
- Fix exit code for record+probe_libc_inet_pton.sh 'perf test' entry (Sandipan Das)
- Fix code dump when using transaction events with 'perf stat -T' (Thomas Richter)
- Do not call perf_dafault_config() twice in 'perf record' (Yisheng Xie)
- Fix top.call-graph config variable processing in 'perf top' (Yisheng Xie)

perf test: Fix exit code for record+probe_libc_inet_pton.sh
This fixes record+probe_libc_inet_pton.sh from always exiting with code
0 and making the test pass even if the perf script output does not match
the expected pattern.
The issue can be observed if this test is run with the verbose flags as
shown below:
