perf probe: Try to use symbol table if searching debug info failed (2015-08-21 12:57:20 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Fix segfault using 'perf script --show-mmap-events', affects
only current perf/core (Adrian Hunter).
- /proc/kcore requires CAP_SYS_RAWIO message too noisy, make it
debug only (Adrian Hunter)
- Fix Intel PT timestamp handling (Adrian Hunter)
- Add Intel BTS support, with a call-graph script to show it and
PT in use in a GUI using 'perf script' python scripting with
postgresql and Qt (Adrian Hunter)
- Add checks for returned EVENT_ERROR type in libtraceevent, fixing
a bug that surfaced on arm64 systems (Dean Nelson)
- Fallback to using kallsyms when libdw fails to handle a vmlinux file,
that can happen, for instance, when perf is statically linked and
then libdw fails to load libebl_{arch}.so (Wang Nan)
Infrastructure:
- Initialize reference counts in map__clone() (Arnaldo Carvalho de Melo)
