Here is a respin of previously posted patches that remove pinned DTR per-cpu TLB requirement. Instead we use DTC to map that translation. With these two patches, we measured substantial performance gain on a database benchmark, in the vicinity of 1.6%. I've also done extensive performance measurement on two other industry standard benchmarks (cpu, java), and have found to have small gain on those workloads. Detail description in the follow on patches. - Ken - : 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
