Subject[PATCH v3 0/3] perf: add option to limit callchain stack scan to increase speed
Date
v2->v3:
- Fix the commit log in the second patch which causes "git am" to fail.
- Remove the 1st patch in v2 as the problem will be fixed by another
patch from Arnaldo.

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 - Streamline the append_chain() function to make it run a bit
faster.
Patch 2 - Add a --max-stack option to perf-report to speed up its
processing at the expense of less backtrace information
available.
Patch 3 - Add a similar --max-stack option to perf-top.

Waiman Long (3):
perf: streamline append_chain() function
perf-report: add --max-stack option to limit callchain stack scan
perf-top: add --max-stack option to limit callchain stack scan
