Sorry, was something different. I've tried to turn the sparse tree into a big patch (is there an easy way to do this btw?). Documentation/dontdiff excludes too much giving me a incomplete xenlinux tree, which in turn generated build errors looking much like it takes the wrong (native) include files. I've seen that in the past with O=, so I blamed it first ... cheers, Gerd -- Gerd Hoffmann
