And it's quite dopey that it's a macro. We should turn it into a real function which caches its return result and goes BUG if it's called before cpu_possible_map is initialised. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
