Naveen N. Rao 0b3c2264ae perf symbols: Fix kallsyms perf test on ppc64le ... ppc64le functions have a Global Entry Point (GEP) and a Local Entry Point (LEP). While placing a probe, we always prefer the LEP since it catches function calls through both the GEP and the LEP. In order to do this, we fixup the function entry points during elf symbol table lookup to point to the LEPs. This works, but breaks 'perf test kallsyms' since the symbols loaded from the symbol table (pointing to the LEP) do not match the symbols in kallsyms. To fix this, we do not adjust all the symbols during symbol table load. Instead, we note down st_other in a newly introduced arch-specific member of perf symbol structure, and later use this to adjust the probe trace point.
