OK. I tried a few kernel builds, but I guess a GCC bootstrap takes a while longer ;) The other thing is most of our systems now have 1T segments, which means you're less likely to take an SLB miss in the first place. Though we do have disable_1t_segments for turning them off, precisely to test this kind of code. cheers
