OK, I see.  This cleans it up nicely. New patch attached.

Done.

Do the changes have no impact to non-Xen non-x86 kernels?
Since xenlinux/ia64 is transparently paravirtualized,
the changes looked like they might be xen-specific, and
xenlinux/ia64 has been running out-of-tree without any
of those changes, the script moves them aside.  If there's
no impact, I can move them back in (but will probably
do so slowly for testing purposes).

In any case, drivers/xen definitely is not yet fully
archdep, so I need to use the pre- or post-mkbuildtree
to do some patching in the short term.  Agree in the longer
term, these files should be empty but if you don't mind
greatly, having the archdep hooks there will probably
make things easier for arch's for now.

OK, let me know if this is better.

Thanks,
