RE: [Xen-ia64-devel] RE: [PATCH]Allow different config file forxenlinux on same arch

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

I support the patch but I think it should be accepted
and committed by someone in Cambridge or Xensource because
it affects important common (and Xen/x86) build files.
Try resubmitting it to xen-devel.

However, I think the best answer is to figure out what's
wrong in the generic config file and fix that.
