I would actually argue that they're scattered all over the place and it will be hard to be sure that we have all the SWAPs we need and only the SWAPs we need. Particularly to continue ensuring that given that most development will be with minios having same endianness as Xen. In short: it's ugly and unless someone really cares it will rot. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
