Still valid?
The bug is probably latent there, but I don't think it can affect anything in the kernel because nothing in the kernel should change NX status as far as I know. Where did you see it? Anyways I would prefer to only clear the PMD NX when NX status actually changes on the PTE.Can you do that change? Anyways; it's really not very important. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
