Subject: [PATCH 0/4] perf tools: Back [vdso] DSO with real data

hi,
this patchset adds data behind the [vdso] map as a special DSO.
This is helpful for dwarf unwind, because now we can unwind
samples taken from [vdso] map. Example output is given in
patch 4/4.

Patch 1/1 fixies separate issue.

Attached patches:
  1/4 perf tools: Do backtrace post unwind only if we regs and stack were captured
  2/4 perf tools: Add memdup function
  3/4 perf dso: Make dsos__find function globally available
  4/4 perf tools: Back [vdso] DSO with real data

thanks,
jirka
