Sure. I'm re-basing my test branch right now and can exclude this one since it is in x86.git. (and yes, I'm interested in unifying mpparse_*.c some day) yes, your understanding is correct -- this is not urgent 2.6.24 material, it is just a 'regular patch':-) Re: making the VIA part into dead-code I had avoided that originally because I was going to nominate this patch for the highest check-in-comment length/code-change ratio But once I went over 1 line I blew the budget;-) Eric, What do you suggest we do with NR_IRQS on i386 so that we can delete the compression code entirely? thanks, -Len -- 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/
