So it seems "map" may not load the symbol out of ".text".
This need to be fixed, since the map is widely used in the perf.

OK, I found a root cause of this issue.
dso__process_kernel_symbol() (which invoked from map__load() path) only adds the
symbols in ".text" section to the symbol list. It must be fixed.

Thank you,
