  perf symbols: Demangle cloned functions (2013-09-25 12:58:21 -0300)

----------------------------------------------------------------
perf/urgent fixes:

. It was possible to use an uninitialized buffer when reading
  kernel modules information and checking if the file was a
  /proc/sys/kernel/kptr_restrict'ed one, fix for this from
  Adrian Hunter.

. The libbfd demangler doesn't handle cloned functions (e.g. symbol.clone.NUM),
  feed it unsuffixed symbol names, workaround from Andi Kleen.

. Fix segfault in 'perf trace' when processing perf.data files with PERF_RECORD_MMAP2
  records, recently added but not handled in this tool, from David Ahern.

. Fix libdl related build in old systems like Fedora 12, from David Ahern.

. Make 'perf kmem' work again on non NUMA machines, fix from Jiri Olsa.

. Fix probing symbols with optimization suffix in 'perf probe' where some
  operations that are entirely user level and involves vmlinux/DWARF were working
  but when the symbol name was fed to the kprobes tracer, the in kernel code
  would use /proc/kallsyms where the name had the suffix, from Masami Hiramatsu.
