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.
