Frederic Weisbecker f4a2a0d9a4 ftrace: add a script to produce a hierarchical view of a function trace ... This script parses a function trace and then produces a hierarchical view of the function call stack after processing it into a tree. Changes on V2 thanks to the trace sent by Steven: - Support both the files "trace" and "trace_pipe" (comments and space differences) - Correct the mini HOW-TO at the beginning.
