The question is whether > we should remove the whole thing, or just the ia64 component? It doesn't do anything for me on sparc64. As per the change description, it's a benefit also on platforms like x86 where context-switch == tlb flush anyways. At least that was my understanding. If it's beneficial to the ia64 folks, I'm ambivalent, so just put the fixed version back in once available.
