sh: oprofile: Fix up and extend op_name_from_perf_id().
op_name_from_perf_id() currently returns a local variable, which isn't terribly productive. As we only handle a single PMU case for now, simply allocate and free the string from the arch init/exit context and have op_name_from_perf_id() hand back the cached string. This also takes UTS_MACHINE in to account, given that we build for multiple architectures. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
