We do want to keep a very tight handle on bloat in per-cpu allocations. By definition the total allocation is multiplied by the number of cpus. Only ia64 has outrageous numbers of cpus in a single system image today ... but the trend in multi-core chips looks to have a Moore's law arc to it, so everyone is going to be looking at lots of cpus before long. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
