Subject: [PATCH v2 0/2] tracing: Add an option to show symbols in _text+offset for function profiler

Hi,

This series implements an option to show symbols in _text+OFFSET
format instead of symbol name in the function profiler.
This is the 2nd version, the 1st one is here;

https://lore.kernel.org/all/175826135058.101165.7219957344129610147.stgit@devnote2/

This version adds a patch to expand the trace_iterator_flag flag
bits to 64 bits [1/2] because there is already 32 flags and no space
to add a new flag. Also, add a dummy TRACE_ITER_PROF_TEXT_OFFSET to
fix a compliation error if CONFIG_FUNCTION_PROFILER=n.

Thank you,

---
