Maybe something like: > > PPC_BOOK3S_PERF_CTRS and PPC_BOOK3E_PERF_CTRS (or > PPC_SERVER_PERF_CTRS / PPC_EMB_PERF_CTRS) We can do that once we have code to support the Freescale embedded PMU and we know how much of arch/powerpc/kernel/perf_counters.c is or isn't useful there. We don't have to get to the final state in one patch. I'd rather put this patch in as-is and then see a patch series that adds the Freescale embedded PMU support and makes whatever Kconfig changes are necessary later.
