    kernel: clean up USE_GENERIC_SMP_HELPERS · 351f8f8e
    Amerigo Wang authored
    For arch which needs USE_GENERIC_SMP_HELPERS, it has to select
    USE_GENERIC_SMP_HELPERS, rather than leaving a choice to user, since they
    don't provide their own implementions.
    Also, move on_each_cpu() to kernel/smp.c, it is strange to put it in
    For arch which doesn't use USE_GENERIC_SMP_HELPERS, e.g.  blackfin, only
    on_each_cpu() is compiled.
