Subject: [PATCH v2 0/2] perf report: Support annotation of code without symbols

For perf report on stripped binaries it is currently impossible to do
annotation. The annotation state is all tied to symbols, but there are
either no symbols, or symbols are not covering all the code.

We should support the annotation functionality even without symbols.

The first patch uses al_addr to print because it's easy to dump
the instructions from this address in binary for branch mode.

The second patch supports the annotation on stripped binary.

 v2:
 ---
 Fix a crash issue when annotating an address in "unknown" object.

Jin Yao (2):
  perf util: Print al_addr when symbol is not found
  perf annotate: Support interactive annotation of code without symbols
