Subject[PATCH 0/16] perf: various symbol resolution fixes, including .opd section use.
Date
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).
