> Yeah, if it was ia64-only, it's a non-issue these days. It's dead and > in pure maintenance mode from a kernel perspective (if even that). There's not much "simultaneous" in the SMT on ia64. One thread in a spin loop will hog the core until the h/w switches to the other thread some number of cycles (hundreds, thousands? I really can remember). So I was pretty generous with dropping cpu_relax() into any kind of spin loop. Is it time yet for: $ git rm -r arch/ia64 -Tony
