Thanks, > > Sanity booted and moderately tested on 64-cpu and 128-cpu Niagara2 > systems. thanks David! btw., this has the CONFIG_HAVE_UNSTABLE_SCHED_CLOCK changes from Peter which should improve things on Niagara2. Note that cpu_clock() still has sync overhead - this will simply go away, once we are reasonably sure about the current sched_clock() code on x86. Those bits still need more testing. Ingo
