So maybe it's just me because it's Friday and I'm on vacation, but I don't see anything overly specific to ppc64 here. In fact, you use get_cycles_rate for all of powerpc in a later patch in the series.
Is there something special about HAVE_GET_CYCLES that I'm missing that would make it only apply to ppc64 and not ppc32?
