perf annotate: AArch64 support (2016-12-01 13:03:19 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

New features:

- Support AArch64 in the 'annotate' code, native/local and
cross-arch/remote (Kim Phillips)

- Allow considering just events in a given time interval, via the
'--time start.s.ms,end.s.ms' command line, added to 'perf kmem',
'perf report', 'perf sched timehist' and 'perf script' (David Ahern)

- Add option to stop printing a callchain at one of a given group of
symbol names (David Ahern)

- Handle cpu migration events in 'perf sched timehist' (David Ahern)

- Track memory freed in 'perf kmem stat' (David Ahern)

Infrastructure:

- Initial support (and perf test entry) for tooling hooks, starting with
'record_start' and 'record_end', that will have as its initial user the
eBPF infrastructure, where perf_ prefixed functions will be JITed and
run when such hooks are called (Wang Nan)

- Remove redundant "test" and similar strings from 'perf test' descriptions
(Arnaldo Carvalho de Melo)

- libbpf assorted improvements (Wang Nan)
