tools lib bpf: Fix maps resolution (2016-11-25 11:27:33 -0300)

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

New features:

- Improve ARM support in the annotation code, affecting 'perf annotate', 'perf
report' and live annotation in 'perf top' (Kim Phillips)

- Initial support for PowerPC in the annotation code (Ravi Bangoria)

- Skip repetitive scheduler function on the top of the stack in
'perf sched timehist' (Namhyung Kim)

Fixes:

- Fix maps resolution in libbpf (Eric Leblond)

- Get the kernel signature via /proc/version_signature, available on
ubuntu systems, to make sure bpf proggies works, as the one provided
via 'uname -r' doesn't (Wang Nan)

- Fix segfault in 'perf record' when running with suid and kptr_restrict
is 1 (Wang Nan)

Infrastructure:

- Support per-arch instruction tables, kept via a static or dynamic table
(Arnaldo Carvalho de Melo)
