Right, so the current fallback case is pretty much the optimal case for the RISC machines, which ends up with generic code being better off not using it much and instead preferring __this_cpu if there's more than one. I mean, its absolutely awesome these things are 1 instruction on x86, but if we pessimize all other 20-odd architectures its just not cool. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
