RE: [PATCH]Allow different config file for xenlinux on samearch

Tian, Kevin
Hi, Keir,
        Any comments upon following patch? ;-) We need it to further check in a specific configuration file (likely xen0_defconfig_ia64tiger) later to run xen on IA64 tiger box. Currently we have no generic one for all IA64 boxes. Let's know if better way to do it. Currently custom with tiger box can only get that file out of the tree.

Thanks,
Kevin
