In fact I have one. Just we offer the users the choice to boot 32bit distributions with 64bit kernels too, in case they only need a single application that needs 64bit or similar. I'm also prepared to rip out or ignore very obscure parts of the 32bit emulation (in fact I did that already), but if it's used commonly or even called in bootup it should be supported. Short term I will just settle on getting that message away so that RedHat users won't bother me anymore. Can you suggest a good way to handle SIOCGIWNAME?

I understand why you don't see much point to run 32bit on Itanium because of the performance. But that's not a problem on all 64bit ports... -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
