Subject: [GIT PULL 0/8] perf/core improvements and fixes

Hi Ingo,

	This one gets us to pass .c files that gets built and
loaded, next step will be to be able to access function arguments,
for which there are patches available, but I'm still reviewing them.

	Please consider pulling,

- Arnaldo

  perf unwind: Pass symbol source to libunwind (2015-10-29 17:48:38 -0300)

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

New features:

- Allow passing C language eBPF scriptlets via --event in all tools,
  so that it gets built using clang and then pass it to the kernel via
  sys_bpf() (Wang Nan)

- Wire up the loaded ebpf object file with associated kprobes, so that
  it can determine if the kprobes will be filtered or not (Wang Nan)

User visible:

- Add cmd string table to decode sys_bpf first arg in 'trace' (Arnaldo Carvalho de Melo)

- Enable printing of branch stack in 'perf script' (Stephane Eranian)

- Pass the right file with debug info to libunwind (Rabin Vincent)

Build Fixes:

- Make sure fixdep is built before libbpf, fixing a race (Jiri Olsa)

- Fix libiberty feature detection (Rabin Vincent)
