Considering that perf and its subcommands have so many parameters, the
documentation is always the first stop for perf beginners. Fixing some
spelling errors will relax the eyes of some readers a little bit.

NOTE: The mapped_size is generally either the same as unwind_data_size (if the unwinding data was mapped in memory by the running process) or zero (if the unwinding data is not mapped by the process). If the unwinding data was not mapped, then only the EH Frame Header will be read, which can be used to specify FP based unwinding for a function which does not have unwinding information.
