Kevin ---
I've accepted and pushed to xen-ia64.bkbits.net all of your
patches except this one. Since this impacts common code
in a "temporary" way, I suspect Keir would reject it.
Please start a thread on xen-devel to discuss the right
way to make dom0_ops.c more friendly for arch-dep features
and we'll see what Keir and the Xen core maintainers
think.

I'll leave it to Matt to explain this in more detail.
Thanks,
Dan
