Hmmm... I thought this would only describe the size of the bit field in the page flags. But it sseem that this also determines MAX_NUMNODES which sizes several kernel arrays amoung them the per node arrays of the slab allocator. So this change would lead to more memory use. However, without this change generic kernel configurations will not work on all IA64 machines. Also why is this set to 8 if we just have 64 processors by default? This means the default configuration would be 256 nodes but only 64 processors? Could we set these limits consitently to the largest IA64 configuration to make sure that a generic IA64 kernel is able to run on all machines? For that ZONES_SHIFT needs to be 10 and NR_CPUS needs to be 1024. - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
