OK, I have merged this with the latest xen-unstable and
updated xen-ia64-unstable with the merge.
I wasn't able to boot multiple domains with the result,
but it was probably pilot error (I will start over from
scratch and retry). But it is also possible that another
xen-unstable change in the last two days has broken
xen/ia64 multiple domain support again. :-(
Could you test with xen-ia64-unstable tip? If it works
for you (or if I get it to work on my retry), I will ask
Keir to pull. If not, could you look through the xen-unstable
csets since the last working version?
Thanks,
Dan
