v1->v2:
- Include a compilation fix patch and a code streamlining patch
into the patch set.
- Use the __stringify() macro in stringify.h instead of adding a
duplicate macro.
- Add the --max-stack option to perf-top as well.
This perf patch set contains the following changes:
Patch 1 - Fix a perf tool compilation error that happens on SLES 11
sp3 system.
Patch 2 - Streamline the append_chain() function to make it run a bit
faster.
Patch 3 - Add a --max-stack option to perf-report to speed up its
processing at the expense of less backtrace information
available.
Patch 4 - Add a similar --max-stack option to perf-top.
