It's a single global variable access: #define cache_line_size() (boot_cpu_data.x86_cache_alignment) Or do you mean it caused cache misses? boot_cpu_data is cache aligned and practically read only, so there shouldn't be any false sharing at least. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
