Subject: [PATCH v2 00/16] perf: various symbol resolution fixes, including .opd section use.

1-4,6,7 are small cleanups.

5 fixes a potential segfault.

8 fixes a use after free for dso->long_name

9 avoids a segfault in elfutils when a truncated elf is loaded.

10 properly tracks that a dso had symbols loaded from a vmlinux image

11-16 fix handling of the '.opd' section in the presence of debuginfo. They
      should also fix plt symbol synthesis (haven't seen the plt issues in
      practice).

Changes from v1:
 - rebased on top of
   git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git  perf/core
 - In #2, make the symbols have size 0 instead of 1.
