2009-11-05sh: perf events: Preliminary callchain support.Paul Mundt
This implements preliminary support for perf callchains (at the moment only the kernel side is implemented). The actual implementation itself is just a simple wrapper around the unwinder API, which allows for callchain generation with or without the dwarf unwinder.
