I don't know if this here is affected:Yes, I think it is. You're clearly expecting the read to actually happen when you call get_hpsb_generation(). It's clearly not a busy-loop, so cpu_relax() sounds pointless / wrong solution for this case, so I'm now somewhat beginning to appreciate the motivation behind this series :-)
