Hello,
This is v4 for libunwind callchain post processing speed up. It was
able to reduce 50% of processing time by using global cache provided
in libunwind. In this version, I decided to use the existing
callchain_param.record_mode instead of adding a new field in the
symbol_conf.
The patch 4 and 5 are just cleanups so that we can easily find out
that which part of code uses the thread-priv.
You can also get it from 'perf/callchain-unwind-v4' branch on my tree:

This is v4 for libunwind callchain post processing speed up. It was

The patch 4 and 5 are just cleanups so that we can easily find out
