This patch set contains two minor fixing for parsing symbols.

The first patch changes to use program header for parsing symbols of
user space executable and shared objects.  Since kernel's symbol parsing
is more complex than userspace for support both kernel symbols and module
symbols, this is why this patch set uses conservative way and doesn't
change kernel symbols parsing.

The second patch is to detect symbols from '.gnu.warning.*' sections,
these symbols are used for linker warning, skip to record them to
avoid spurious symbols.

Changes from v1:
- Changed to use program header / PT_LOAD segments to parse symbols for
  userspace executable and shared object files (Fangrui).


Leo Yan (2):
  perf symbol: Correct address for bss symbols
  perf symbol: Skip recording symbols in '.gnu.warning.*' sections
