Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

 * 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.
