Currently, oprofile support is only functional if CONFIG_HW_PERF_EVENTS is set. If this symbol is not set, oprofile initialisation will fail at runtime. Instead of allowing the oprofile code to build but fail at runtime it seems less confusing to not allow the code to be built unless hardware performance counter support is available.
