I agree that it's an ugly hack.  But please consider two things:

1. If you look at the revision history for xen-mkbuildtree-pre (at the
   link I posted above) you'll see that it's down from 12 files to
   2 in the past month.  We're working hard on getting rid of it
   completely.

2. The two files that are left have zero chance of confusing your
   patching process.  One is regenerated on every build
   (asm-xsi-offsets.h).  The other is planning to be moved soon.

Now I'm the one that's confused!  :-(

I don't have a different repository.  I have a temporary
xen-ia64-unstable tree ported to 2.6.17-rc5-git6 (at the moment) so
I could generate linux-2.6-xen.patch.  The repository I have
personally is only for the purpose of prototyping this effort.

At this point I'm working on going from prototyping to integration,
which means that instead of using my temporary tree, we'll use the
xen-unstable tree that you have already ported.  xen-unstable and
xen-ia64-unstable were synced just a couple days ago so it should work
well on ia64.

Thanks for looking at the changes.  I'll work on eradicating
xen-mkbuildtree-pre, but it will probably take a few days at least.
