Hm, no. This is a backport of the loader changes only, in order to make
it possible to boot a HEAD kernel plus Xen on a 10 world (and to make it
easier to MFC other loader changes to 10). The stable/10 kernel is still
not able to run as Xen Dom0, so the port is correct.

That's why I haven't added 'Relnotes: yes' to the commit message :).

Roger.
